IEEE C37.012:2022

IEEE Guide for the Application of Capacitive Current Switching for AC High-Voltage Circuit Breakers above 1000 V

Standard Details

Committee/Society: IEEE Power and Energy Society/Switchgear

Abstract: Guidance for the application of ac high-voltage circuit breakers switching capacitive currents is provided. The general theory of capacitive current switching and the notions of restrike, reignition, and nonsustained disruptive discharge (NSDD) are addressed in the application guide. Voltage factors used for single-phase testing as a substitute for three-phase testing are explained. The application of circuit breakers for different network conditions and different capacitive loads (capacitor banks, cables, transmission lines, and filter banks) is discussed.

Keywords: application, capacitive current switching, high-voltage circuit breakers, IEEE C37.012, inrush current, nonsustained disruptive discharge, NSDD, overvoltages, reignition, restrike
