Station Service consists of 1-PH 34.5kV-240V 100KVA Transformer with Z=6% and Losses = 2kW. Feed to a motor is 240V 1-Phase, #6CU, 300FT. Long, with 10HP motor (10kVA) load. Total remaining load on Sta. Service is 800kVA. Assume all load has a 0.80 power factor. Assume the 34.5kV bus is regulated to 1.03 per unit and system impedance is negligible. Motor NP states Locked-Rotor code F.Assume inrush @ 0.6 pf. The above Station Service is upgraded to 3-PH bank 34.5kV-240V 100kVA each, same rating as the above connected delta-delta. With the load redistributed to a balanced load for the transformer bank, what would be the resulting voltage at the transformer low-side terminals and motor terminals while starting?
