<p style="text-align:justify"><span style="font-size:14px">The term &ldquo;Static Relay&rdquo; refers to a sensing device which uses active semiconductor devices such as P-N junction diodes, transistors, ICs etc. for processing the signals from output of C. T. and/or P. T. in order to obtain the desired relay characteristics discussed earlier. The final slave relay may be an attracted armature type electromagnetic relay or it may be a solid-state device.</span></p>
