question

The following data apply to a 100-kW 250-V six-pole 900-rpm compound generator (long-shunt connection): No-load rotational losses = 3840 W Armature resistance at 75°C = 0.012\Omega Series-field resistance at 75°C = 0.004\Omega Commutating-pole field resistance at 75°C = 0.004\Omega Shunt-field current = 2.60 A Assume a stray-load loss equal to 1% of the output and calculate the rated-load efficiency.
