Abstract: Some trouble frequently occurred in 220 kV system AC voltage circuit of substation, which may impact on the safe operation of the secondary devices, even can cause the protection malfunction. Especially, the reverse charging in secondary circuit of the potential transformer may lead serious accident. Through the practical example analysis of a reverse charging of potential transformer, the consciousness on the serious accident caused by fault in AC voltage circuit was raised. The measures to avoid the reverse charging accident were proposed. 
