Revision of IEEE C37.011 Guide for the Application of Transient Recovery Voltages for AC High-Voltage Circuit Breakers

A revision of IEEE C37.011 was done from 2008 to 2011 to improve the content of the 2005 edition on TRV interpolation for terminal fault, line fault, transformer limited fault and reactor limited fault. Another aim was to introduce class S1 and S2 circuit breakers for rated maximum voltages of less than 100 kV.

I. Introduction

This document presents and explains the main changes approved in 2011 to IEEE C37.011 Guide for the Application of Transient Recovery Voltage for AC High-Voltage Circuit Breakers [1].
