What Is Current Differential Relay at Betty Metzger blog

What Is Current Differential Relay. In between the two cts, the relay coil is simply connected at the equipotential position so that. Current differential relays are connected at both terminals in the differential core which, in the event of an internal fault, trip the circuit breakers in their respective stations. Thus a current differential relay is one that compares the current entering a section of the system with the current leaving the section. The basic principle of a differential relay is the comparison of two or more currents entering and leaving a particular section of a. No further trip command communication between the stations is therefore required. The relay whose operation depends on the phase difference of two or more electrical quantities is known as the differential protection relay. The two cts in the above circuit are utilized at every end of the section to be protected. It works on the principle of comparison between the phase angle and the magnitude of the same electrical quantities.
