Relative to lightningdisturbance and short-circuit faults, the chopped wave caused by lightning-induced weak faults is obvious.
相对于雷电干扰和普通短路故障，雷击引起弱故障时的行波截波特征非常明显。
2
The accuracy grade of frequency collection is improved, the function modular to prevent lightning and electromagnetic disturbance of signal and power source is added.
提高了频率采集的精度等级，增加了信号及电源防雷击和抗电磁干扰功能模块。
3
The inductive voltage of the thunder and lightning and the produced disturbance voltage when the inductive load turns on or is separated from the power network is main disturbance pulse voltage.
