Answer / sandeep vazhoor

Typical power circuit configuration involves 3 phase diode
rectifier at the input to convert the AC input to DC
voltage, LC or C filter to reduce the ripple in the DC
voltage. 3 phase IGBT inverter stage converts this DC
voltage into variable voltage variable frequency output as
per the desired pattern.

What are test values for an 63 KVA and 100 Kva Distribution Transformers for the following typical tests 1)Magnetic balance 2)Short circuit test 3)Open Circuit test 4)Vector group confirmation test .please give me the standard values for all the above tests.
