| Abstract: | An B-phase instant earthing fault happened on the 500 kV Shanhua circuit No.2 of 500 kV Ling-xianshan substatoin. One of the two circuit breakers （C/B） of this circuit failed to reclose and tripped three phases C/Bs while another C/B reclosed normally. With analyzing series of relay protectoin actuations during the fault, and demonstrating relevant simultations, the reasons that causes such mis-operatoin is found. Corresponding counter measures are drawn.. |
