零火线都带电什么原因?怎么处理?JEM电机引接线电气二次电路图中的电压回路编号方法

What's the reason for the line of zero fire line and how to deal with it?

零火线都带电什么原因?怎么处理?具体情况不好说，但从经验来看一种是偏相了造成零线带电，这种情况在电网中不可避免，零线带的电压也不会太高，只要不是偏相偏的太离谱不影响正常使用。还有一种是断了零线就比较麻烦了，以我们普通的楼房例子，一种 ...

The zero line are charged for what reason? How to deal with the specific circumstances? Not to say, but from experience is a partial phase caused by the zero line charged, this power is inevitable, with the zero line voltage is not too high, as long as not too outrageous offset does not affect the normal use. Another kind is the trouble of breaking the zero line, with the example of our ordinary building, one kind of..
