Improving Generator Reliability

One session of the 7EA User Conference dealt with generator reliability. The factors affecting reliability include the unique characteristics of each machine, its age/condition, history, operational and operator actions (cycling, loading, trips, restarts, synchronous condensing, motoring and so on), environment, external events and acts of god. The smart policy is to form a maintenance plan and carry it out systematically.
