并且根据接地电阻的大小选择不同的暂态能量算式,故可判断金属性接地故障和高接地电阻接地故障。
Zero-sequence transient energy is calculated for low earthing resistance and single-phase transient energy for high earthing resistance.
在高电阻率地域,将接地电阻降到设计值非常困难。
In the high resistivity area, it is very difficult to reduce the earthing resistance to the given value.
