Relay protection closer to the fault point
Distance relay protection is a critical aspect of electrical power network transmission and distribution systems. Its primary function is to detect and isolate faults by measuring the impedance (or distance) between the relay location and the fault point. When the fault occurs at point X in the protected zone then the voltage drops while current increases. Some of the advantages of distance relays. Good and reliable selectivity of the protection is essential in order to limit the supply interruption to the smallest area possible and to give a clear indication of the faulted part of the network.
