i have faced a problem in ro plant grunfos make bm30type pump it is 22kw pump. We start this pump using siemens 3rw 4423-ibc44, 30kw softstarter but this soft starter will frequently failier so we planed to change dol starter. So pls tell anybudy its possible or not.

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 ?
