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 resistance was higher than critical resistance field winding was wrongly connected field system lost residual magnetism there was a break in the armature circuit field resistance was higher than critical resistance field winding was wrongly connected field system lost residual magnetism there was a break in the armature circuit ANSWER DOWNLOAD EXAMIANS APP
