1. A three-phase star-connected load is supplied from the delta-connected secondary of a transformer. If the transformer line voltage is 190.5 V and the load phase current is 10 A, calculate the transformer phase current and the load phase voltage. 2. A 20 kW, 415 V three-phase star-connected load takes a line current of 34.8 A. Calculate the PF of the load.
