Hi,
Hope someone can help - I've got to calculate the readings given off the instruments (voltmeter, ammeter and wattmeter) for a transformer when it's subject to an open circuit test and a short circuit test (open circuit test performed on the low volatge side, the short circuit test on the high voltage side). The details of the transformer below:
400 / 40 v
2 kVA
50 Hz
Core loss resistance 2 kΩ
Magentising reactance 3 kΩ
High voltage winding:
Winding resistance 2Ω
Inductive reactance 3Ω
Low voltage winding:
Winding resistance 0.025Ω
Inductive reactance 0.025Ω
Am stuck as what equations to use to do these calaculations, so any help will be greatly appreciated!!
Thanks,
Stu
