This guide is intended to help the relay engineer understand the application considerations when applying breaker failure protection (BFP) to power
Guide for Breaker Failure Protection of Power Circuit Breakers
This guide describes methods to protect a power system from faults that are not cleared because of failure of a power circuit breaker to operate
Guide for Breaker Failure Protection of Power Circuit Breakers
本标准活用于设计成能对电气设备内部的线路提供保护的“设备用断路器”(CBE)的这种型式的机械开关电器。 注1:术语“设备”包括了器具在内。 注2:被保护的元件一般为电动机、变压器以及内部接线等。 设备用断路器可具有比过载条件要求高的额定短路能力, 此外还有具有一个与规定的短路保护电器(SCPD
