we have taken HV test of 2.5 k and Megger test on 11 kv HT cable.here it shows no fault but when we are charging the same cable with 11 kv supply why the VCB 11 kv gets tripped can anybody define the possible cause of fault ?

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 ?
