A 20 kW, 440 V, long shunt, compound dc generator has a full load efficiency of 87 %. If the resistance of the armature and interpole is 0.4 ohm and that of the series and shunt fields are 0.25 ohm and 240 ohms respectively. Calculate the following: Output of the prime mover = kW Power developed in the armature = kW Total Copper Losses = kW Combined bearing friction, windage and core loss = kW
