Shenhua Guangdong Guohua Yuedian Taishan Power Generation Co., Ltd.(Guohua Taidian for short) produced electricity since 2002. The electric equipments for coal transportation ran stably, and there was no power failure in the whole bus before July 2013. After that time, 2BCB10 power switch had some grounding failures in 2BCB stage in 6kV switch cabinet, that caused 6kV two-stage bus lost power at the wharf. The paper summarized the failure working process and the failure analyse methods, and found the ultimate reason caused the failures, that provided the good reference for the failures processing for the future.
