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 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 ANSWER DOWNLOAD EXAMIANS APP

Electrical Machines Two synchronous generators operating in parallel 200 MW and 400 MW respectively. The drooping characteristics of their governors are 4% and 5% from no load to full load. Consider the governors operating at 50Hz on no load. How will the machine share, if the load is 600 MW? generator 2 gets over load 200 MW and 400MW generator 1 gets over load None of these generator 2 gets over load 200 MW and 400MW generator 1 gets over load None of these ANSWER DOWNLOAD EXAMIANS APP
