Question

1. A three-phase transformer with Yd connection, 300 kVA, 12000/220 V, has been short-circuit tested on the high voltage side giving the following results: 750 V, 14.434 A, 10838 W.
When the transformer is connected to nominal voltage without load it consumes 5400W.

Calculate:
to. Relative voltages of short circuit high voltage side: εcc, εRcc and εXcc.
b. The voltage in the secondary when the transformer is connected to nominal voltage and feeds a load of 200 kW fp = 0.8 in delay.
c. Apparent power of maximum efficiency and maximum efficiency with fp = 0.95 inductive.

solve WITHOUT using artificial intelligence.
