Current direction at relay protection fault point
Consider a fault occurs at a point P. Hence the fault current flows from the generator G through the breaker A and E. Also the fault current comes from the breaker series A . This White Paper describes the sense, the potentials and the use of directional protection and directional zone selectivity functions, hereafter called “D” and “SdZ D” respectively. This selective operation helps avoid unnecessary tripping of circuit breakers and ensures that only the faulty section is isolated. Directional relays are not just overcurrent devices with extra logic. They compare current from CTs with voltage from PTs to determine the fault direction. I care. This practice-oriented paper shows, in addition to the illustrative explanation of the basis of ground fault parameters in insulated and arc-suppression-coil-ground systems, the connection variants for determination of the ground fault direction in detail.
