摘　　要：白马垅变电站于1995年元月7日发生由于直流电源“一点”瞬时接地而误跳闸。通过多次模拟试验发现是由于变电站滤波电容在接地瞬间的暂态过程所引起的。In1. 7. 1995 A misoperation of a breaker in Bai Ma Long Substation was taken place by reason of 'one point 'instant grounding in the direct circuit. The root source that we found out through simulated test many' times was the transient current produced by the direct circuit grounded instantly owing to the filter capacitors assembled the power supply supplying all equipments in the substation.
