General Information
The operation of a single engine electric set is quite straightforward. When two or more electric sets are operated in parallel, the techniques become more complicated. However, an understanding of the principles and practices described in the following pages should help the operator.
Mechanical and hydraulic governors commonly used with engine electric sets will be described. Their operating characteristics during single unit and parallel operation will also be discussed, with examples of various governor combinations. Electric-hydraulic and electronic governors are given a short description.
Fundamentals of alternating current generators, also called alternators, will be followed by descriptions of single unit and parallel unit operation. This will include bringing a unit on the line in parallel with others, transferring load to the incoming unit, and taking a unit off the line. The function of the voltage regulator in the operation of alternators is described.
