零序是一种接地故障检测方法,它使用一个传感器(CT)来把所有相导体和中性导体连接在一起,传感器会按照线路中接地故障电流的不平衡程度等比例地产生输出,再由一台继电器来测量这一输出,并断开断路器或释放接地故障警报。

And the bond order you get out will either be, for example, zero, which would mean that you have no bond, 5 or you could have 1, a single bond, 1 . 5, a 1 and 1/2 bond, 2, a double bond, and so on.
你得到的键序要么是比如说是零,这意味着没有键,或者你会得到1,单键1。,1又二分之一键,2,一个双键,等等等等。
