Example 26.28. A long-shunt compound-wound generator gives 240 volts at F.L. output of 100 A. The resistances of various windings of the machine are: armature (including brush contact) 0.1 , series field 0.02 , interpole field 0.025 S2, shunt field (including regulating resistance) 100 №. The iron loss at F.L. is 1000 W; windage and friction losses total 500 W. Calculate F.L. efficiency of the machine.
