A 3-0, 50 Hz load is receiving (80+j80) KVA operating at 5KV Line-to-Line. A Y-connected capacitor bank is connected in parallel with the load to correct the pf to 0.9. Thus the total KVAR that must be supplied by the capacitor bank is and the capacitance per phase is 0 A 40 MVA 40 KV. 60 Hz. three-phase synchronous generator has a synchronous reactance of 5 0/0, and negligible armature resistance. At a certain excitation, the generator delivers rated load, 0.8 pf lagging to an infinite bus bar at a line-to-line voltage of 40 KV. Calculate the armature current. O a (800-1600) A = 1L-36.87 KA O b. (461.6 +j346.4) A = 0.576 +36.87° KA Oc. None of these O d. (461.6-j346.4) A = 0.576 -36.87 KA Oe.
