Method for exercising a stand-by electrical generator
DCFirst Claim
1. A method of exercising an engine-driven, electrical generator, the generator generating a predetermined output voltage at a predetermined frequency with the engine running a predetermined operating speed, the method comprising the steps of:
- selecting a generator exercise mode for the generator;
starting the engine; and
running the engine at a predetermined exercise speed, the exercise speed being less than the predetermined operating speed.

Abstract
A method is provided for exercising an engine-driven, electrical generator. The generator has a first operation mode wherein the generator generates a predetermined output voltage at a predetermined frequency with the engine running a predetermined operating speed and a second exercise mode. The method includes the step of running the engine at a predetermined exercise speed with the generator in the exercise mode. The predetermined exercise speed is in the range of 40% to 70% of the predetermined operating speed of the engine. In addition, in the exercise mode, the generator generates an exercise voltage that is less than the predetermined output voltage.
