Question:

A 50-kW, 250-V short-shunt compound generator has 0.06-Ω armature resistance, 0.04-Ω series field resistance, and 125-Ω shunt field resistance.

a.) Calculate the induced armature voltage at rated load and terminal voltage. Assume the total brush-contact drop is 2V.

b. If the total mechanical and core loss is of the generator is 1.8 kW, calculate the generator efficiency at full load.

c. At what load does the generator achieve maximum efficiency?

d. What is the value of this maximum efficiency?
