The transformer has been tested to determine its equivalent circuit. The results of the tests
are:
Open-circuit test
Voc = 12.47 kV
Ioc = 0.5 A
Poc = 900 W
Short-circuit test
Vsc = 300 V
Isc = 50 A
Psc = 2.5 kW
The load on the transformer is 100 kw at 0.9 p.f. lagging and 2350 v:
What is the voltage at the power source of the system?
b. What is the voltage regulation of the transformer?
How efficient is the overall power system?
