Abstract :
A method of measuring the temperature rise of the rotor of a large (500MW) generator is described in this paper. The method makes use of a direct current comparator, which enables accurate measurements to be made from a few percent up to beyond 100 percent of rated field current. The measurements were made while the generator was being used under various conditions of load and cooling.
