Electrical Machines A dc shunt generator, when commissioned after a major repair of the field system, failed to build Up voltage. It was because field system lost residual magnetism field winding was wrongly connected there was a break in the armature circuit field resistance was higher than critical resistance field system lost residual magnetism field winding was wrongly connected there was a break in the armature circuit field resistance was higher than critical resistance ANSWER DOWNLOAD EXAMIANS APP
