Description / Abstract:
This recommended practice covers the selection and application of controllers and automation to industrial and commercial power systems. It is likely to be of greatest value to the power-oriented engineer with limited experience with this equipment. It can also be an aid to all engineers responsible for the electrical design of industrial and commercial power systems.
The present edition of this recommended practice focuses on the application of ANSI/NEMA design controllers. There are differences in the design of IEC controllers which require additional application considerations which are beyond the scope of the present edition.
