O d. 0.25 + 12.5, 12.4 +j124, 12 + j120 Clear my choice For the question below, consider a 125MVA, 15.5 kV generator with a subtransient reactance and a negative sequence reactance of 0.2 p.u and a zero sequence reactance of 0.03A. The TD OC relay used to protect against SC faults with service factor of 110% and pick up setting of 115% of full load current has: Select one: O a. TS = 5, TDS = 0.5 b. TS = 6, TDS = 1.5 O C. TS = 6, TDS = 0.5 O d. TS = 5, TDS = 1.5 Consider the system below with a generator, transformer and the equivalent of a system. The CT ratio on the generator's side and the base current (on a base of 100MVA, 22 kV) are respectively equal to
