Abstract
The protection of power factor correction capacitors used to enhance electrical system efficiency is addressed. Different considerations in the selection of capacitor fuse applications and the philosophies behind them are reviewed. Individual and group fusing are discussed. Continuous current, transient current, fault current, tank rupture curve coordination, voltage on good capacitors during a fault, energy discharged into a failed unit, outrush current, and coordination with unbalance detection schemes are topics covered. Examples of actual applications of capacitors in industrial distribution systems are presented. >
