what will happen if field winding supply of synch generator
accidently got disconnected?
Answer Posted / deepak mishra
if field winding is disconnected then generator is not
build up bcz there is no any flux in the air gap so no flux
will be cut by armature conductor and at the same time no
emf will be induced
i think raghavendram wrong bcz obove condition occur when
prime mover is disconnected and excitation remains on..

what kvrah y we need to take the readind of that
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 ?
