摘要
由于现有录波器都是以大接地电流系统为主而设计的 ,没有考虑小接地电流系统的特性 ,为了便于低压系统故障分析 ,现在逐步加装故障录波器 ,但目前国内几种故障录波器都不能满足小接地电流系统运行条件 ,就此问题提出了改进方法。
Because recording wave equipments have been designed according to the large electric current of earthing system,and haven't been considered in the specific property of the little electric current of earthing system now,so,in order to easy to be analyze the breakdown of the little electric current of earthing system,many substations have installed the recording wave equipments step by step.But all types of recording wave equipments in our country now can't satisfy the operation conditions in the little electric current of earthing system.So the improving project for the question is put forwand.
