What do we use in Motor core laminations..???CRGO or
CRNGO..and why..????

Answer Posted / deepak

CRNGO ,

Depending on the wattloss ,you have to select the
corresponding grade of CRNGO.

CRGO are used in tranformers

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 ?
