Saturation of Current Transformer is the major problem of Bus Protect in power system.
电力系统母线保护存在的主要问题，是电流互感器的饱和问题。

A new countermeasure to current transformer (TA) saturation, namely, current polarity comparison method, for differential current protection of transmission line is proposed.
提出了一种适用于输电线路差动保护抗电流互感器(TA)饱和的新方法——电流极性比较法。
