PC37.012 - Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V
This document revises the application guide for capacitance current switching for high-voltage circuit breakers rated in accordance with IEEE Std C37.04? 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.
IEEE 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 re-strike, 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.
IEEE C37.012-2014/Cor 1-2016 - IEEE Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers above 1000 V - Corrigendum 1
This corrigendum addresses a change in Equation (26) and the list of variables belonging to this equation.
IEEE C37.012a-2020 - IEEE Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V Amendment 1
Covered in this amendment are changes in di/dt limitations for non-oil circuit breakers. A section has been added describing possible delayed current zeros when doing a rapid close?open of a line circuit breaker (CO) when shunt reactors are connected to a line or cable. Some minor errors have been corrected and references have been updated.
