Question

How is the specific electric loading related to copper losses and temperature rise?

(a) high specific electric loading gives high copper losses and high temperature rise

(b) high specific electric loading gives low copper losses and high temperature rise

(c) high specific electric loading gives high copper losses and low temperature rise

(d) high specific electric loading gives low copper losses and low temperature rise

I had been asked this question in my homework.

This interesting question is from Synchronous Machines Output Equation in portion Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Correct answer is (a) high specific electric loading gives high copper losses and high temperature rise

To elaborate: The specific electric loading is directly proportional to the copper losses and the temperature rise. The high specific electric loading gives high copper losses and high temperature rise.
