摘要
Abstract
Misoperation of breakage flashover protection of 220 kV or above circuit breaker for large generator-transformer set and breaker protection failure for large generator are generally caused by unreasonable setting calculations, which leads to false protecting actions many times. The more reasonable setting calculation method and several problems needed to notice in setting calculation are put forward.关键词
