IEEE C37.012-2005 - IEEE Application Guide for Capacitance Current Switching for AC High-Voltage Circuit Breakers

Standard

Superseded

Standard Details

Guidance for the application of ac high-voltage circuit breakers for capacitance current switching is provided. The document addresses the general theory of capacitance current switching, the notion of restrike, reignition, NSDD and voltage factors are explained. Application of circuit breakers for different network conditions and different capacitive loads (lines, cables, capacitor and filter banks) is treated.

Active Projects	Active PC37.012a - Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V Amendment Changing the Capacitive Inrush/Outrush Limitations of Switchgear This document revises the application guide for capacitance current switching for high-voltage circuit breakers rated in accordance with IEEE Std C37.04(TM) 1 and listed in IEEE Std C37.06(TM). It supplements IEEE Std C37.010(TM). Circuit breakers rated and manufactured to meet other standards should be applied in accordance with application procedures adapted to their specific ratings.
Existing Standards	Active C37.012-2014 - IEEE Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V Guidance for the application of ac high-voltage circuit breakers is provided. The application guide addresses the general theory of capacitance current switching; and the notions of restrike, re-ignition, non-sustained disruptive discharge (NSDD). Voltage factors used for single-phase testing as substitute for three-phase testing are explained. Application of circuit breakers for different network conditions and different capacitive loads (capacitor banks, cables, transmission lines, and filter banks) is treated.
