There is a series of accessories and components Oust as incase of low voltage capacitor banks) which are assembled with high voltage capacitor units to form a composite equipment, which functions efficiently, when connected to power system net work for power factor correction (reactive power compensation). This assembly is designated as Capacitor bank.
Capacitor banks are either FIXED type or AUTOMATIC and are complete with equipment for protection against malfunctioning when connected to power system net work. The selection of the type of capacitor bank and its configuration, totally depends on cost factor. This document discuss the various types of banking configurations and components fitted, to serve as a guideline for easy selection of best type of equipment, which would meet the requirement of a particular power system.
