Abstract
Protection of shunt capacitor banks in electric power delivery systems using protection settings determined by the protection device or an independent system using capacitor bank arrangement data is described herein. Capacitor bank arrangement data may be entered into an intelligent electronic device (IED). The IED may determine protection settings for the capacitor bank arrangement and for fail-open and fail-short scenarios using the arrangement data. The protection settings may be loaded into a protection element, which applies protection using signals from the power system. Upon detection of an unbalance condition, the IED may effect a protective action by opening a circuit breaker to disconnect the capacitor bank from the power system.
