Dealing with a Breakdown of a Middle Impedance Bus Current Differential Relay

HUANG Xue-yun (Chongqing Nan’Power Supply Bureau, Chongqing 400060 )  
This article by clearing the break-down of the relay ,analyses the acting principle of the Subsection breaker of the PMH-114 middle impedance bus current differential relay made in Xu-chang Relay Factory and also suggests reasonable break-down searching and analysing methods. Meanwhile, the relay protection personnel are warned to pay more attention to protect and examine the middle impedance bus current differential relayat times to avoid the like trouble.
