Question 2 (a) Figure Q2(a) shows the percentage differential relay used for the protection of an alternator winding. The relay has minimum pickup current of 0.15 A and a percentage slope of 12%. A high resistance ground fault occurs near the grounded neutral end of the generator winding with the current distribution as shown in Table Q2(a). Identify with reason whether the relay will operate. I I CB wiłu 400/5 400/5 iz mhu Figure Q2(a) Table Q2(a) Student Name I2 (A) ID (A) 370 300
A single phase synchronous generator was open-circuit and short-circuit tested. During an opencircuit test of the synchronous machine, nominal voltage of 220 V was obtained for the fieldcurrent of IfNL = 6 A while for short-circuit test, rated current of 8 A was reached for the fieldcurrent of IfSC = 5 A. The synchronous generator is connected to rated voltage of 220 V.Assuming negligible armature resistance determine: a. internal voltage E (behind Xs), under rated current and power factor of 0.8 lagging;b. for the internal voltage from (a) determine the steady-state stability limit.Note: Xs is ratio of IfSC / IfNL
