The figure Fig. Q1 (e) shows the percentage differential relay used for the protection of an alternator winding. The relay has a minimum pick up current of 0.N ampere and has a percentage slope of 10%. A high resistance ground fault occurs near the grounded neutral end of the generator winding with the current distribution as shown. Assume a CT ratio of 400: 5; determine whether the relay will operate. Let, N is equal to the last non-zero digit of your student ID. 360 + j 0.0 Ꮎ 0000000000 그 Fig. Q1(e) 320+ 0.0 [1]
