Question

370) A shunt generator has a full-load current of 100A at 220V. Stray losses are 1000W and the shunt field current is 12A. The armature resistance including the brushes is 0.055 ohm. Calculate the efficiency of the machine. 360.) A shunt generator has an output of 6.6 kw at 100V. The Rsh is 25 ohms and the Ra is 0.05 ohm. If the overall efficiency is 89%, the combined core, friction, and windage losses is equal to?

Step 1

370) First, we need to calculate the input power to the generator: P_in = V_in x I_in P_in = 220V x 100A P_in = 22,000W Show more…
