It consists of&nbsp;<em>branches</em>&nbsp;that are labeled with either frequencies or probabilities. Tree diagrams can make some probability problems easier to visualize and solve. The following example illustrates how to use a tree diagram:</span></span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\"><strong>EXAMPLE&nbsp;3.24</strong></span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">In an urn, there are 11 balls. Three balls are red (<em>R</em>) and eight balls are blue (<em>B</em>). Draw two balls, one at a time,&nbsp;<strong>with replacement</strong>.&nbsp;<em>With replacement</em>&nbsp;means that you put the first ball back in the urn before you select the second ball. Therefore, you are selecting from exactly the same group each time, so each draw is independent. The tree diagram shows all the possible outcomes.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16239179121623917912.jpg\" style=\"height:438px; width:800px\" /></span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\"><strong>Figure&nbsp;3.10</strong>&nbsp;Total = 64 + 24 + 24 + 9 = 121.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">The first set of branches represents the first draw. There are 8 ways to draw a blue marble and 3 ways to draw a red one. The second set of branches represents the second draw. Regardless of the choice on the first draw, there are again eight ways to draw a blue marble and 3 ways to draw a red one. Read down each branch to see the total number of possible outcomes. For example, there are 8 ways to get a blue marble on the first draw, and eight ways to get one on the second draw, so there are 8 &times; 8 = 64 different ways to draw two blue marbles in succession. Each of the outcomes is distinct. In fact, we can list each red ball as&nbsp;<em>R</em>1,&nbsp;<em>R</em>2, and&nbsp;<em>R</em>3 and each blue ball as&nbsp;<em>B</em>1,&nbsp;<em>B</em>2,&nbsp;<em>B</em>3,&nbsp;<em>B</em>4,&nbsp;<em>B</em>5,&nbsp;<em>B</em>6,&nbsp;<em>B</em>7, and&nbsp;<em>B</em>8. Then the nine&nbsp;<em>RR</em>&nbsp;outcomes can be written as follows:</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\"><em>R</em>1<em>R</em>1,&nbsp;<em>R</em>1<em>R</em>2,&nbsp;<em>R</em>1<em>R</em>3,&nbsp;<em>R</em>2<em>R</em>1,&nbsp;<em>R</em>2<em>R</em>2,&nbsp;<em>R</em>2<em>R</em>3,&nbsp;<em>R</em>3<em>R</em>1,&nbsp;<em>R</em>3<em>R</em>2,&nbsp;<em>R</em>3<em>R</em>3.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">The other outcomes are similar.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">There are a total of 11 balls in the urn.

Electrical power is generated at 15.75 kV (210 MW) and stepped up to 220 kV using generator transformer (GT). This power is transmitted at 220 kV (GT secondary voltage and transmission voltage decided by economic choice as discussed earlier). As the power to be transmitted further is less, economic voltage is 66 kV (say) now. Therefore, power is stepped down at receiving substation shown in figure 6.1. There are many equipments (not shown in figure) in this substation as discussed. Only power transformers (220/66 kV, 150 MVA) are shown. Capacities shown in figure 6.1 are typical. 66 kV transmission line terminates at 66/11 kV distribution substation. Economic choice might have been stepping down to 132 kV at receiving substation. In that case, transformation would have been 220 kV to 132 kV and 132 kV transmission further. Then there would have been 132/66 kV intermediate substation and 66 kV transmission as in figure 6.1.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">In distribution substation, voltage is stepped down to 11 kV (the distribution voltage). 11 kV feeders feed the pole mounted transformer or distribution transformer (11 kV/415 V). These distribution transformers are protected by drop-out (DO) fuse on primary side of transformer and by fuse or (in modern times) by MCCB (Molded Case Circuit Breaker) on secondary side of transformer. This protective gear is decided by economic reasons to be discussed later. 415 V distributors finally feed power to consumers.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Until this power system operates normally, there are no problems. But faults and abnormalities are inevitable, and these will damage the equipment of power system network. Hence faults are to be cleared as quickly as possible. This function is carried out by components of protective gear [protective relays, circuit breakers, transducers (CT and PT) and related control circuit].</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">There is a limit to the amount that can be spent on protective gear. Thumb rule says that protective relaying equipment shall not cost more than 5 % or at the most 10 % (if the equipment to be protected is very costly and important) of the total cost of equipment to be protected. Table 6.1 shows the break-up of costs of components of switchgear for protection of typical equipment. As circuit breaker is a device which is needed to manually make and break the circuit, it is a usual practice not to consider its cost in protective gear.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<table align=\"center\" cellspacing=\"0\" class=\"MsoTableGrid\" style=\"border-collapse:collapse; border:none\">\n	<caption>\n	<p><strong><span style=\"font-size:20px\">Table 6.1: Costs of Switchgear Components for Protecting An Equipment</span></strong></p>\n	</caption>\n	<tbody>\n		<tr>\n			<td style=\"border-bottom:1px solid black; border-left:1px solid black; border-right:1px solid black; border-top:1px solid black; vertical-align:top; width:274px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">&nbsp;Total Cost of Equipment to be Protected</span></div>\n			</td>\n			<td style=\"border-bottom:1px solid black; border-left:none; border-right:1px solid black; border-top:1px solid black; vertical-align:top; width:189px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">100 %</span></div>\n			</td>\n		</tr>\n		<tr>\n			<td style=\"border-bottom:1px solid black; border-left:1px solid black; border-right:1px solid black; border-top:none; vertical-align:top; width:274px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">Protective Relays</span></div>\n			</td>\n			<td style=\"border-bottom:1px solid black; border-left:none; border-right:1px solid black; border-top:none; vertical-align:top; width:189px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">0.55 %</span></div>\n			</td>\n		</tr>\n		<tr>\n			<td style=\"border-bottom:1px solid black; border-left:1px solid black; border-right:1px solid black; border-top:none; vertical-align:top; width:274px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">Control Panels and Associated Wiring</span></div>\n			</td>\n			<td style=\"border-bottom:1px solid black; border-left:none; border-right:1px solid black; border-top:none; vertical-align:top; width:189px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">0.40 %</span></div>\n			</td>\n		</tr>\n		<tr>\n			<td style=\"border-bottom:1px solid black; border-left:1px solid black; border-right:1px solid black; border-top:none; vertical-align:top; width:274px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">Control Room</span></div>\n			</td>\n			<td style=\"border-bottom:1px solid black; border-left:none; border-right:1px solid black; border-top:none; vertical-align:top; width:189px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">0.12 %</span></div>\n			</td>\n		</tr>\n		<tr>\n			<td style=\"border-bottom:1px solid black; border-left:1px solid black; border-right:1px solid black; border-top:none; vertical-align:top; width:274px\">\n			<div style=\"text-align:center\"><span style=\"font-size:28px\">Transducers (C.

Whenever a fault occurs on the feeder, C. T. transmits the fault current to current coil of a protective relay. (For a relay such as directional or distance relay, P. T. transmits the faulted voltage to the potential coil of the relay). The protective relay operates as per its characteristics (instantaneous, definite time or inverse time) and its contact closes [R-1 in figure 6.2 (b)].</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Referring to figure 6.2 (b), R-1 closing, coil of tripping relay (86) energizes. The current capacity of contact R-1 is 1 or 2 amp. The trip coil (52-TC is a trip coil of circuit breaker) current is of the order of 15 to 20 amp d. c. Hence R-1 operates 86 and the contact 86-1 is used to trip the breaker as contact 86-1 can be designed to carry and break large current (20 amp d. c.). The measuring relay contact cannot be designed to carry and break such a large current as this heavy contact will reduce the sensitivity of the relay. The tripping relay also does the multiple functions such as annunciation, alarm, interlocks etc. [(not shown in figure 6.2 (b)].</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">52-a is a mechanical switch associated with breaker. Usually, 8 NO and 8 NC contacts (switches) are provided by breaker manufacturer. These contacts are designed to carry and break large current. Hence when breaker is closed, NO contact 52-a is closed.

Protective relay contacts are usually self-reset contacts, hence on tripping of a breaker, current through breaker becomes zero, R resets and R-1 opens. But 86 is usually a lock-out relay (hand-reset). Hence 86-1 remains closed until manually reset. If 52-a were not provided, 52-TC will remain energized. Trip coils are intermittent duty coils and are not designed to remain energized continuously. Hence the function of 52-a is to disconnect trip coil circuit, because when breaker trips 52-a will open. </span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">While reading any control circuit, it should be remembered that it is an international norm of drawing that all relays are shown deenergized, all breakers are shown open, all isolators are shown open, all switches are shown open in the drawing. Also, every electrical component of protective relaying system and protective relays are numbered as per international codes for drawing. &nbsp;</span></p>','','1','6.4','Basic Tripping Circuit','1','2','1','0','1','2021-07-01 05:02:44','2021-11-03 15:50:14'),(2341,101,'<p>6.5 Zones of Protection</p>','','single','html','<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251263211625126321.jpg\" style=\"height:585px; width:800px\" /></p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251263771625126377.jpg\" style=\"height:1097px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251264051625126405.jpg\" style=\"height:1134px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">As seen in figure 6.1, a power system consists of many equipments (e. g. generators, transformers, transmission lines, busbars etc.), it is divided into number of protective zones for the purpose of protecting it.

Less the probability of failure of protective system, better is its reliability. The advent of modern numerical relays (with their many new features like self-diagnosis of internal failure of part or full of its circuitry containing discrete components and microprocessor or digital signal processor, storage of pre-fault and post-fault data, circuit breaker failure protection, indication of location of fault in transmission line etc.) has made a protective system much more reliable than the earlier electromechanical or static relays. With these numerical relays, the power system is available for more numbers of hours in a year than earlier technology of protection. This increases the revenue earned by electricity company and industries and this modern technology adds to the comfort and convenience of consumers.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><u><strong>Selectivity</strong>:</u> Selectivity means isolation of minimum faulty section from the rest of the healthy system. This requirement demands that only faulty portion is isolated and healthy power system keeps on feeding normal power to consumers.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong><u>Speed:</u></strong> It is obvious that faster the protective system (protective relays and associated breakers) operates, less will be the damage to equipment. As such, the equipments are short-time (1 or 3 second) rated for high fault currents and therefore there will be practically no damage to the equipment if the relays and breakers operate fast. Breaker time as fast as 1 or 2 cycles is possible with the advent of SF<sub>6</sub> and vacuum breakers.</span></p>\n	</li>\n</ol>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">Fast relay operation is possible but the requirement of selectivity (in case of remote back-up protection, the back-up relay has to wait until the primary relay operates as we shall study) and speed are contradictory. Such contradiction can be addressed by numerical relays having facility of reverse interlocking.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">Another important reason why the protective system should be fast can be appreciated by consideration of power system stability. The relays and breakers should operate before transient stability limit of generators operating in the system is reached. That means the fault must be cleared before critical clearing time decided by stability considerations. If the relays operate after that time, the generator poles will slip, they will be disconnected from bus due to operation of pole slipping protection and this will further deteriorate system stability, threaten the remaining generators to go out of step and finally resulting in cascaded tripping in the worst case. This would lead to dark out in the state grid.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">Lastly, the relays should not be made to operate faster than one cycle as otherwise they may unnecessarily operate due to transient conditions like lightning and switching surges.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<ol start=\"4\">\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong><u>Discrimination:</u></strong> A protective relay should be able to discriminate between a fault and an overload. It should be able to discriminate between a fault and load conditions even when the minimum fault current (under the condition of minimum number of generators connected to the power system) is less than maximum load current (with maximum number of generators connected).</span></p>\n	</li>\n</ol>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">When a power transformer is switched ON, it will take a magnetizing inrush current, which in the worst case can be 10 times its rated full load current. This inrush exponentially decays to normal value after 15 to 30 cycles depending upon X/R ratio. This is neither fault nor abnormality. This behaviour is part of normal operation of transformer. Unfortunately, the fault current for an internal fault within the transformer may be less than this inrush current.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">As the fault path is an arc within the oil filled transformer, it is highly hazardous because oil is inflammable. Such a fault has to be cleared within a couple of cycles. This is made possible by feature (of protective relay) known as second harmonic stabilization using which operation of relay is blocked in case of inrush function. But fault current, in certain cases contain second harmonics and hence this feature of harmonic restraint is to be unblocked.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">In modern interconnected systems, conditions like power swings can mislead a distance relay to mal-operate while protecting the transmission lines.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">In case of differential protection, the protective relay should operate only for internal fault very sensitively and should be stable for external faults. But this is never so simple as the non-identical C. T. saturation characteristics result in a spill current due to severe through (external) fault and differential relay may mal-operate. Also, the relay can never be connected at equipotential points in differential protection scheme because of geography of the location. This gives rise to unwanted relay operation. This requires discriminatory features in the protective scheme.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">In case of generator protection, field failure relay should not operate for either pole-slipping conditions or due to power swings. Similarly, a reverse power relay for generator protection should operate for failure of prime-mover only and not for internal faults in the generator (in which case there is a current reversal from bus to generator which looks like reverse power).</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">No protective scheme should trip a breaker when a fuse placed in secondary of potential transformer fails.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">Therefore, it seems that a protective relay should operate when current, voltage or power (or flux or frequency or angle between current and voltage) deviate from given limit. But relay operating criteria is not as simple as this. The criteria is to be so chosen that a relay should operate only under the conditions it is required to operate and should never operate under conditions against which the power system does not require interruption. Many of such conditions look like fault (or more severe than faulty conditions) where relay operation is not anticipated.</span></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<ol start=\"5\">\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong><u>Stability:</u></strong> Stability is a quality required only for differential protection by virtue of which the protective scheme is sensitive for internal faults within the unit to be protected and stable for external faults out of the protection zone of the equipment.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong><u>Sensitivity:</u> </strong>Sensitivity refers to the minimum level of fault current at which a protective relay operates</span></p>\n	</li>\n</ol>','','1','6.6','Requirements of Protective System','1','2','1','0','1','2021-07-10 08:39:53','2021-11-03 15:52:56'),(2343,101,'<p>6.7 Main and Back-up Protection</p>','','single','html','<p style=\"text-align:justify\"><span style=\"font-size:14px\">Main or primary protection schemes are used in the first line of defence. There must be second line of defence provided by certain back-up schemes. There can be a fault in transmission line, a fault in transformer, an induction motor or a generator, the components of switchgear protect the equipment against the damaging consequences of such faults. But then, very obviously, there can be troubles and faults within these components of protective gear (relay coil may be open circuited, in numerical relay, a digital signal processor does not work or some discrete component has failed, trip coil of the breaker has become open-circuited or there is some trouble in operating mechanism or gas pressure has reduced in SF<sub>6</sub> circuit breaker so that it does not trip even after receiving signal from relay, C. T. and/or P. T. are not properly transforming fault current and faulted voltage due to some trouble in them so that finally a relay does not get correct information of fault, everything is healthy but the coil of auxiliary tripping relay has open-circuited or control circuit fuse has failed). In this case the fault will not be cleared. Hence back-up protection is a must. There are three kinds of back-up protections used in practice:</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<ol>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>Relay Back-up:</strong> In this kind of back-up scheme, a protective relay and its C. T. core are duplicated. This is a very costly protection scheme and used for very important and costly equipment. Low forward power protection of large generators uses this relay back-up scheme.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>Breaker Back-up:</strong> When a feeder breaker fails to trip on a fault in a feeder, the feeder fault becomes virtually a bus fault. In breaker back-up scheme, a busbar protection scheme is initiated in this case and all breakers of the bus (but a breaker that has failed) will trip. This will be discussed at length in buszone protection.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>Remote Back-up:</strong> Remote back-up is provided by a relay in the next section towards the source. This scheme of back-up is cheapest because it incurs no cost.

If it is desired to change the time of operation of the relay at same current magnitude, TMS (time-setting) can be varied. If the time of operation of relay for the current I amp is t seconds with TMS = 1.0, time of operation of the relay for the same current with TMS = 0.5 will be 0.5 t seconds. The operating time is usually specified in seconds at PSM = 10 and TMS = 1.0.</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\">Resetting time: The time within which the relay returns to its normal state from its fully operated state, once the current is discontinued, is known as resetting time.

But due to mechanical inertia in the electromechanical relays and due to electrical inertia provided by inductance of relay circuitry (current does not immediately reduce to zero, once the current is discontinued, but reduces to zero exponentially), the relay keeps on counting time for a short while (before start of reset).

The unit (IAS) is provided with a normally closed heavy duty contact. Under normal (no-fault) condition, a C. T. secondary current will not pass through the trip coil of the breaker. When the IDMT unit operates (or high-set unit operates), IAS is energized, IAS-1 opens, C. T. secondary current flows through the trip coil, breaker trips and fault is cleared.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<ol start=\"6\">\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>&nbsp;Voltage Controlled Normal Inverse IDMT Overcurrent Relays:</strong></span></p>\n	</li>\n</ol>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251270141625127014.jpg\" style=\"height:780px; width:800px\" /></p>\n\n<p style=\"margin-left:72px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">In case of comparatively smaller sized generators for which automatic voltage regulators are not provided, if a fault occurs, the steady-state fault current is less than CMR of the generator as the synchronous reactance is more than 100 %. This is particularly true in case of fault in transmission line and line relay and back-up overcurrent relay placed in secondary of GT fails. The back-up overcurrent relay in this case is in third line of defence and hence considerable delay in time of operation. By this time, the generator impedance has entered in steady-state region reducing the value of fault current below CMR of the generator. Under this condition, a simple inverse time overcurrent relay cannot be set. Voltage controlled overcurrent relay, in this case, will solve the problem of setting. The relay offers two time-current characteristic curves. First curve offers overload protection of the generator under normal voltage condition. When a fault occurs, voltage collapses below 70 % of rated voltage, which automatically shifts the plug-setting of a relay to 40 % of its original value. Thus, pick-up current is reduced which allows the operation of the relay at reduced fault current below CMR. Also, the time of operation of the relay at higher PSM gets reduced. The second curve, hence, offers the back-up protection for line fault as discussed. These two characteristic curves are shown in figure 6.9.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<ol start=\"7\">\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>&nbsp;Long Time Inverse IDMT Overcurrent Relays: </strong></span></p>\n	</li>\n</ol>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:72px; text-align:justify\"><span style=\"font-size:14px\">These relays can be used for the dual (overcurrent cum overload) purpose.

A contact of protective relay energizes an auxiliary tripping relay the contact of which, in turn, completes the trip coil circuit. But if trip coil of the circuit breaker is open-circuited, the whole operation explained above will not be able to energize the trip coil of the breaker and the breaker will not trip. Hence a fault will not be cleared. Therefore, it is essential to check the integrity of a trip coil of any breaker at all times (24&nbsp;&times; 7)&nbsp;Checking or supervising the integrity of a trip coil is not only necessary when a breaker is closed (which is obviously understood as non-clearance of fault is hazardous) but also when a breaker is open. This is because the breakers have two separate coils: a closing coil and a tripping coil. Energization of closing coil results in closing the power contacts of a breaker and energization of tripping coil results in tripping of a breaker. Now when one is closing a breaker on fault (i.e., closing a breaker when a fault is already existing in an equipment to be protected) and a trip coil is not healthy, fault will not be cleared. Therefore, supervision of integrity (healthiness) of a trip coil of a breaker, irrespective of whether a breaker is open or closed, is very essential.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251271851625127185.jpg\" style=\"height:780px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">This is done by trip circuit supervision relays. An arrangement for this purpose is shown in figure 6.10. Assuming d. c. control supply to be 220 V d. c., auxiliary relay A is 220 V d. c. relay (i.e., it operates if 220 V d. c. is applied across its coil) and auxiliary relay B is 110 V d. c. relay. If the breaker is closed, 52-a<sub>1</sub> is closed. If the trip coil is healthy, relay A is energized energizing relay C (220 V d. c. relay) through contact A-1. An alarm will not be sounded as the NC contact of relay C opens out. Should the trip coil be open-circuited, A will not energize, C remains deenergized and alarm is sounded to let the control room staff know the fact. They should replace the trip coil. If the circuit breaker is open, 52-a<sub>1</sub> is open, but 52-a<sub>2</sub> is closed. Now relay coils of relays A and B will be in series if trip coil is healthy. 110 V d. c. is applied across both the relay coils. However, relay A will not operate as it is not getting sufficient voltage, but relay B will operate, B-1 will close, C is energized, and alarm will not be sounded. Alarm will be sounded if trip coil is unhealthy.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<ol>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\"><strong>&nbsp;Annunciators:</strong></span></p>\n	</li>\n</ol>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:48px; text-align:justify\"><span style=\"font-size:14px\">In major substations and power plants many kinds of faults and abnormalities occur.

When fault occurs, the circuit breaker clears the fault by receiving the signal from the protective relay. But as 85 % faults are transient, the recloser relays will close the circuit breaker after 0.3 second which is a flashover time. Within this time, the protective relay must have reset as if it is a sustained fault, resetting of the protective relay fully is a requirement for selective tripping. A static relay resets much earlier to this time (0.3 second). An electromagnetic relay takes a very long time to reset. Typical resetting time of induction disc type electromagnetic relay giving normal inverse characteristic at TMS 1.0 is around 10 seconds and that of extremely inverse IDMT overcurrent relay is of the order of 26 seconds.

The testing requirements are that the static relay must withstand, without being damaged, a power frequency a. c. high voltage of 2500 V between all terminals shorted on one side and an earthed terminal on the other side. Also, between same terminals impulse voltage of 5 kV, 1.2/50 microseconds is applied and the relay must withstand that.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<ol start=\"2\">\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\">Variation of Characteristics with Temperature and Age: This was a demerit in early days when static relays were introduced.

Whereas, as static relays are having large number of components to connect their circuitry, there is a doubt about their reliability. Careful choice of discrete components, a very strict quality control while manufacturing and accelerated life tests have considerably improved the reliability of the static relays. Figure 6.16 shows the reliability index of static and electromagnetic relays. Electromagnetic relays possess a reliability index of 100 % from the day one of their commissioning. But with passage of time, because of friction, bearing deterioration, deterioration in spring tensions, weakness in magnetic field strengths of permanent magnets etc. will reduce reliability index after 10 years or 15 years (in designs of renowned manufacturers). After about 20 years the reliability would have drastically reduced rendering these relays useless. </span></p>\n	</li>\n</ol>\n\n<p style=\"margin-left:24px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:24px; text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251281591625128159.jpg\" style=\"height:624px; width:800px\" /></p>\n\n<p style=\"margin-left:24px; text-align:justify\">&nbsp;</p>\n\n<p style=\"margin-left:24px; text-align:justify\"><span style=\"font-size:14px\">In static relays, on the other hand, the reliability index is very poor in early years of commissioning because reliability of many components cannot be guaranteed. But if these components are found proven up to 1 or 2 years, then for a very long time (may be 25-30 years or more), nothing will happen to these relays and will serve for many years. Now, if static relays are installed with rated current and voltage conditions for these 1-2 years in the manufacturing industry, reliability further is fully guaranteed. This is not economically viable. Hence accelerated life tests are conducted on relays at elevated current, voltage and temperature in disturbed atmospheric conditions created deliberately (such as high pressure than atmospheric, high humidity etc.) for few days or may be a month which is equivalent to 1-2 years.</span></p>\n\n<p style=\"margin-left:24px; text-align:justify\">&nbsp;</p>','','1','6.16.2',NULL,'1','2','1','0','1','2021-07-01 08:31:01','2021-07-01 14:01:01'),(2364,101,'6.16.3 Basic Integrated Circuits Used in Static Relays','','single','html','<p style=\"margin-left:24px; text-align:justify\"><span style=\"font-size:14px\">The manufacturers prefer to use discrete components like diodes, transistors, resisters, capacitors etc. in the integrated form, ICs.

As static relays cannot handle current of even 1 amp (this current can be even 20 amp when fault occurs), the current is further stepped down to a value usually 25 milliamperes by an input C. T. inbuilt in the static relay. This current passes through a resistor of value 40 ohms provided across secondary of input C. T. Thus, A voltage signal of 1 volt is made available which is equivalent to 1 amp (input to a relay) or 100 amp passing through the line. This signal is rectified so that 1 volt d. c. is fed further to a level detector. Op-amp 741 can be used as a level detector. Output from rectifier is fed to the non-inverting input of an op-amp. Reference voltage to an op-amp is a d. c. reference derived from a variable pot the output of which can be adjusted from 1-20 volts d. c. We have adjusted the pot at (say) 10 V d. c. It is very obvious that if the input from rectifier is more than 10 V, there will be an output available at the output terminal of op-amp. Output is a square wave of +V<sub>CC</sub> and - V<sub>CC</sub> volts. This means that 10 V (and hence 10 amp) is the setting of the relay. Output of op-amp [a pulse sensing circuit or differentiator can be added (not shown in the figure 6.17) between op-amp and an output circuit as a signal of a large band width is not desirable to be fed to the gate of the thyristor] is given to output circuit consisting of a thyristor (or S. C. R., i. e. silicon-controlled rectifier). When a positive rising pulse is fed to a gate of thyristor, it starts conducting and keeps on conducting until its anode circuit is disconnected. The output tripping relay R placed in the anode circuit operates when the thyristor starts conducting. The contacts of this relay can be used to trigger the a. c. tripping relay 86 and contacts of 86 will complete the trip coil circuit of the breaker finally tripping the breaker. Once the breaker trips, 52-a shown in figure 6.17 opens and thyristor stops conducting, resetting the relay.</span></p>','','1','6.16.4',NULL,'1','2','1','0','1','2021-07-01 08:33:13','2021-07-01 14:03:13'),(2366,101,'6.16.5 Static Definite Time Overcurrent Relay','','single','html','<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251284391625128439.jpg\" style=\"height:616px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251284641625128464.jpg\" style=\"height:616px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Once the fault current exceeds the pick-up value decided by overcurrent relay discussed in foregoing section, contact 3-4 will shorted.

As such definite time characteristic can also be obtained. Figure 6.20 shows the block diagram of generalized overcurrent relay. Voltage proportional to current (from C. T. secondary) is first rectified. The output of this rectifier is converted into logarithmic value using the log circuit. The output of this log circuit is amplified n times. (As per requirements of the characteristic. n = 0 gives the definite time characteristic, n = 1 gives IT = K curve and n = 2 gives I<sup>2</sup> t = K curve). In the next stage, there is antilog circuit. The output of antilog circuit is integrated. Op-amp can be used as an integrator circuit. Another form of integrating circuit can be as shown in figure 6.21. The output of integrating circuit is a ramp signal as shown in figure 6.21. The output of integrator is compared with a reference voltage as shown in figure 6.22. When the voltage of the integrator output crosses the reference voltage (which decides the TMS), the level detector gives the output signal which can be given to an output unit for finally generating a trip signal. The charging process in the integrator unit is allowed only if the current is higher than a pre-set threshold (plug-setting). Otherwise, the charging process is suitably blocked.</span></p>','','1','6.16.6',NULL,'1','2','1','0','1','2021-07-01 08:37:06','2021-07-01 14:07:06'),(2368,101,'6.16.7 Two-Input Relays','','single','html','<p style=\"text-align:justify\"><span style=\"font-size:14px\">The two-input relays can be classified as:</span></p>\n\n<ul>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\">An Amplitude Comparator</span></p>\n	</li>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\">A Phase Comparator</span></p>\n	</li>\n</ul>\n\n<ol>\n	<li style=\"text-align:justify\">\n	<p><span style=\"font-size:14px\">An Amplitude Comparator: A two-input comparator relay which compares the magnitudes of two quantities irrespective of their phase relations is known as an amplitude comparator.

One does not have a phase comparator but only an amplitude comparator is available. Yet it is possible to compare the phase angle between quantities A and B. This is demonstrated in figure 6.23. What all one has to do is add and subtract two quantities A and B vectorially. Irrespective of amplitudes of quantities A and B [in figure 6.23(a), |A| &gt; |B|, in figure 6.23(b), |A| &lt; |B| and in figure 6.23(c), |A| = |B|], if angle between A and B Is less than 90<sup>0</sup>, |A + B| &gt; |A -B| and therefore the amplitude comparator relay operates. Similarly, if angle between A and B is equal to 90<sup>0</sup>, the amplitude comparator relay is in threshold condition. For angle more than 90<sup>0</sup>, the amplitude comparator relay blocks the operation. The same is true for a phase comparator relay acting as an amplitude comparator relay. The demonstration of figure 6.24(a), 6.24(b) and 6.24(c) is self-explanatory.</span></p>','','1','6.16.7',NULL,'1','2','1','0','1','2021-07-01 08:41:57','2021-07-01 14:11:57'),(2369,101,'6.16.8 Two-Input Phase Comparator Relay','','single','html','<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251290591625129059.jpg\" style=\"height:499px; width:800px\" /></p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251291051625129105.jpg\" style=\"height:415px; width:800px\" /></p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251291291625129129.jpg\" style=\"height:1155px; width:800px\" /></p>\n\n<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251291971625129197.jpg\" style=\"height:353px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">In directional relays, the phase angle between voltage and current vectors is to be compared. In phase comparator distance relays also, the phase angle between two electrical quantities is to be compared. Two-input phase comparator can be realized by static circuitry as shown in block diagram of figure 6.25. Two inputs A and B are first filtered to avoid harmonics as the distorted waveshape may lead to wrong zero crossing detection. A zero-crossing detector convers the sinusoidal wave into the square wave. The zero-crossing detector circuit is shown in figure 6.26. The zero-crossing detector is an op-amp comparing the input signal with earth as a reference. When the input is more than zero, the output is there, which is a square wave as shown in figure 6.27. The output of zero-crossing detector is differentiated and then rectified to clip off the negative spikes as shown in waveshapes of figure 6.27. Op-amp can be used as a differentiator or alternatively, a circuit shown in figure 6.28 can also be used. The output of the differentiator is fed to the monostable multivibrator, the band width of the square wave being adjusted to 5 milliseconds (90<sup>0</sup> in 50 Hz system). The output of the square wave for both the inputs are fed to an AND gate so that there will be output of the AND gate only if the phase difference between two quantities A and B is less than 90<sup>0</sup>. The output of the AND gate is fed to an output circuit consisting of thyristor via a differentiator. Tripping of a breaker will be established when the thyristor triggers.</span></p>','','1','6.16.8',NULL,'1','2','1','0','1','2021-07-01 08:47:00','2021-07-01 14:17:00'),(2370,101,'A protective relaying scheme comprises of','','multi','single','','','1','6.3',NULL,'4','1,3','1','0','1','2021-06-29 14:33:26','2021-06-29 14:33:26'),(2371,101,'The burden of an overcurrent relay is helpful in deciding...','','multi','single','','','1','6.11',NULL,'2','1,3','1','0','1','2021-06-29 14:35:02','2021-06-29 14:35:02'),(2372,101,'Abnormalities generally occur in...','','multi','single','','','1','6.1',NULL,'3','6','1','0','1','2021-06-29 14:37:16','2021-06-29 14:37:16'),(2373,101,'The major cause of an L-g fault in transmission lines is','','multi','single','','','1','6.1',NULL,'1','6','1','0','1','2021-06-29 09:11:43','2021-06-29 14:41:43'),(2374,101,'The worst consequence of fault occurrence is','','multi','single','','','1','6.1',NULL,'3','6','1','0','1','2021-06-29 14:43:14','2021-06-29 14:43:14'),(2375,101,'The cost of protective relaying system should not exceed','','multi','single','','','1','6.3',NULL,'2','1','1','0','1','2021-06-29 14:46:41','2021-06-29 14:46:41'),(2376,101,'The zone of protection in a power system network is decided by','','multi','single','','','1','6.5',NULL,'4','3,6','1','0','1','2021-06-29 14:48:48','2021-06-29 14:48:48'),(2377,101,'The thermal relays are used in the power system for protection against','','multi','single','','','1','6.10.1',NULL,'1','3','1','0','1','2021-06-29 14:53:04','2021-06-29 14:53:04'),(2378,101,'Instantaneous overcurrent relays operate (if there is a fault) within','','multi','single','','','1','6.10.2',NULL,'2','1','1','0','1','2021-06-29 14:54:35','2021-06-29 14:54:35'),(2379,101,'Overcurrent relay is a','','multi','single','','','1','6.9.1',NULL,'1','3','1','0','1','2021-06-29 14:56:17','2021-06-29 14:56:17'),(2380,101,'The rating of an overcurrent relay is','','multi','single','','','1','6.10.3',NULL,'3','3','1','0','1','2021-06-30 13:01:30','2021-06-30 13:01:30'),(2381,101,'The rating of an overvoltage/under voltage relay is','','multi','single','','','1','6.10.3',NULL,'1','3','1','0','1','2021-06-30 13:03:08','2021-06-30 13:03:08'),(2382,101,'Electrodynamic damage to the electrical equipment occurs if the fault current is twice the CMR of the equipment.','','multi','single','','','1','6.1',NULL,'2','6','1','0','1','2021-06-30 13:04:55','2021-06-30 13:04:55'),(2383,101,'The auxiliary relay is required in the tripping circuit because the protective relay contact cannot take high trip coil current.','','multi','single','','','1','6.4',NULL,'1','3','1','0','1','2021-06-30 13:05:35','2021-06-30 13:05:35'),(2384,101,'The requirements, speed and selectivity of the protective relaying system, are contradictory to each other.','','multi','single','','','1','6.6',NULL,'1','3','1','0','1','2021-06-30 13:06:28','2021-06-30 13:06:28'),(2385,101,'In relay back-up scheme the protective relays are duplicated.','','multi','single','','','1','6.7',NULL,'1','1','1','0','1','2021-06-30 13:07:25','2021-06-30 13:07:25'),(2386,101,'In breaker back-up scheme, two similar breakers are connected in series.','','multi','single','','','1','6.7',NULL,'2','3','1','0','1','2021-06-30 13:08:47','2021-06-30 13:08:47'),(2387,101,'6.12 Refer to the media and select an answer.','','multi','html','<p style=\"text-align:justify\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251297011625129701.jpg\" style=\"height:464px; width:800px\" /></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Refer figure 6.14.

This necessitates installation of transmission lines and distribution network reaching out to all urban and rural areas of the country.

The protective scheme must be very fast and yet selective.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">It is usual practice to protect feeders of 11 kV voltage rating and transmission lines of 66 kV by overcurrent and earth-fault relays as primary (and only) protection as distance protection scheme will not be economically viable for the purpose. 132 kV and 220 kV lines are part of interconnected power system network and forced outage of such lines would cost a lot to generation and transmission companies. Therefore, these lines are protected by more comprehensive distance protection schemes. Very important of these 132 kV and 220 kV lines, 400 kV and 765 kV transmission lines are protected by line differential (carrier current) protection. However, overcurrent and earth-fault relays are used as back-up or secondary relays for protection of such ehv and uhv lines.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">We will discuss about details of overcurrent and earth-fault protection of transmission lines.</span></p>','','1','7','Protection of Transmission Lines By Overcurrent and Earth-fault Relays','1','2','1','0','1','2021-07-01 14:47:17','2021-11-03 16:08:49'),(2411,101,'<p>7.1 Radial Feeder Protection</p>','','single','html','<p style=\"text-align:justify\"><span style=\"font-size:14px\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251311251625131125.jpg\" style=\"height:1086px; width:800px\" /></span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Any transmission system can be subdivided into segments of radial feeders supplying the consumers. Therefore, our discussion will initiate with a typical single line diagram of a basic radial feeder shown in figure 7.1</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">As we have already discussed earlier, power is generated at 15.75 kV (typical) and stepped up to 220 kV by generator transformer (GT). There is only one generator shown in the figure but in practice, there are more (4 to 8 or more) number of generators operated in parallel in a power plant. The power generation capacity of single unit can be 660 MW or even more. Hence, there will be many 220 kV transmission lines emanating from 220 kV infinite bus. One such line will lead to receiving substation, where voltage is required to be stepped down to (say) 66 kV (optimum transmission voltage for further power transmission. Optimum voltage could have been 132 kV. In that case the transformation would have been to 132 kV and 132 kV lines would run further). Once again, many 66 kV lines will feed power to distribution network in different areas. One 66 kV line (as shown) is feeding power to distribution substation (66/11 kV), wherefrom many 11 kV feeders are feeding power to a PMT (Pole Mounted Transformer) or distribution transformer. This transformer steps down voltage to three-phase 415 V for final requirement of consumers. This is the normal operation of power system.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">But we have seen that faults are inevitable. They do occur. Therefore, protection of this transmission system is a must. The function of the protective relaying system, as we have discussed, is to isolate the minimum faulty section from the rest of the healthy power system as quickly and as selectively as possible. When this isolation is done, we say that the fault is cleared. Rectifying a fault, if it is a sustained fault, is a different task to be taken care of by maintenance staff. Protective relaying system or switchgear is made up of three basic components. Protective relay senses the fault. But a large current of the order of few hundreds or thousands of amperes passing in the transmission line cannot be allowed to pass through a relay. Hence, a current transformer (and/or potential transformer as well for many relays, but in overcurrent protection only C. T.) steps down the current which can be handled by a relay. Fault current interruption can be accomplished by a circuit breaker (C. B.) which receives the signal from the relay. Thus, a protective relay, C. B., and C. T. (and/or P. T.) plus the required control circuitry are said to be the components of switchgear (protective gear or protective relaying system).</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Relays as shown in figure 7.1 are not single units. Figure 7.1 is a single line diagram. Therefore, there are three C. T.s and four relays (or a single relay having three overcurrent units and one earth-fault unit) in a relay group shown R<sub>1</sub>. Hence, relays R<sub>1</sub> protect 220 kV line, relays R<sub>2</sub> protect 66 kV line and relays R<sub>3</sub> protect 11 kV feeder. PMT is protected by D. O. (Drop Out) fuse and 415 V distributor is protected by simple fuse (or MCCB in modern protective scheme). 415 V distributor is not so important as to justify the cost of relays, breaker and C. T.s. Fuse (or MCCB) is a sensing device and current interrupting device as well. MCCBs are available in the range of rated continuous currents ranging from 100 amp to 4000 amp. No doubt, comprehensive characteristics, that the relay provides, are not provided by a fuse (or MCCB) but it is not required and not economical too.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Requirement of selectivity of a protective system demands that only least faulted portion is isolated. Hence, relays R<sub>1</sub>, R<sub>2</sub>, R<sub>3</sub> and a fuse are to be properly graded or coordinated and their settings are required to be properly calculated for optimum selectivity and fast operating time. Therefore, in case of fault in 415 V distributor, fuse (or MCCB) should operate to isolate the faulty section. If fuse fails to trip, relay R<sub>3</sub> will operate as a remote back-up protection to clear the fault. If there is a fault in 11 kV feeder, relay R<sub>3</sub> acts as primary protection and clears the fault. If either R<sub>3</sub> fails to operate or C. T. saturates and does not provide proper information to relay R<sub>3</sub> or circuit breaker (on receiving signal from R<sub>3</sub>) does not trip because of trouble in the breaker (e. g. open-circuiting of trip coil of breaker or failure of operating mechanism etc.), relay R<sub>2</sub> will act as a back-up. Similarly, for fault in 66 kV line, R<sub>2</sub> primarily operates and R<sub>1</sub> gives back-up.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">Hence, our next important discussion is about discriminating the fault location in different sections (i.e. whether the fault is in distributor, 11 kV feeder or 66 kV or 220 kV lines) and procedure of relay setting calculations.</span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\"><img alt=\"\" src=\"https://edupmquestionhelp.s3.ap-south-1.amazonaws.com/hint/uploads/images/16251311981625131198.jpg\" style=\"height:386px; width:800px\" /></span></p>\n\n<p style=\"text-align:justify\">&nbsp;</p>\n\n<p style=\"text-align:justify\"><span style=\"font-size:14px\">For this purpose, we simplify figure 7.1 and remove transformers from the figure 7.1 as shown in figure 7.2.</span></p>','','1','7.1','Radial Feeder Protection','1','2','1','0','1','2021-07-01 11:43:53','2021-11-03 16:16:11'),
