The inverse time delay characteristic is adopted by the basic zero-sequence over-voltage protection. On the basis of the analysis of the transient negative current, a compensated voltage can be generated with multiplying the rms value of the negative sequence transient current of the feeder by a settable compensated reactance, then combined with the magnitude of the zero-sequence voltage to consist of the compounded compensated voltage, which can be utilized to revise the characteristics of the inverse time-delay.

其基本保护采用零序过电压保护，动作时间采用反时限特性；在分析接地故障负序暂态电流分布特点的基础上，利用线路负序电流暂态有效值与一个可整定的补偿电抗相乘，形成补偿电压，并与零序电压幅值合成复合补偿电压，利用该电压对基本的反时限动作特性曲线进行修正，使零序过电压保护具有选择性。
