how we can calculate 2 phase welding transformer rating or total power?
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?

Thank,s and Regard,s. Muhammed Ikram.
my UPS suddenly goes off and all panel light also blow off.This happens even main electric supply is not interrupted.After some time it automatically starts functioning normally.Batteries are new.
