Find the efficiency of a long shunt compound generator rated at 250 kW, 230 V when supplying 76% of rated load at rated voltage. The resistance of armature and series field are 0.009 Ω and 0.003 Ω. The shunt field current is 13 A. When the machine is run as a motor at no load the armature current is 25 A at rated voltage?
