This document revises the application guide for capacitive current switching for high-voltage circuit breakers rated in accordance with IEEE Std C37.04 and tested in accordance with IEEE Std C37.100.2.6 It supplements IEEE Std C37.010. Circuit breakers rated and manufactured to meet other standards should be applied in accordance with application procedures adapted to their specific ratings.
This guide is intended for general use in the application of circuit breakers for capacitive current switching. Familiarity with other US national standards applying to circuit breakers is assumed, and provisions of those standards are indicated in this guide only when necessary for clarity in describing application requirements.
Revision Standard – Active. 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.
