Solved A 20 kW, 440-V, short-shunt, compound dc generator
Question: A 20 kW, 440-V, short-shunt, compound dc generator has a full-load efficiency of 87%. If the resistance of the armature is 0.4 ohm and that of the series and shunt fields 0.25 ohm and 240 ohms respectively, calculate the combined stray power loss of the machine.
