The leakagecurrent must be returned to the source, it will flow through any available thermocouple conductor, line pipe, pipeline, water or earth went to the source.
漏泄电流必需前往至源极,它将流经任何热电偶可用的导体、线管、管道、水或大地前往到源极。
2
The value of this current is limited by earthleakage resistance of the return circuit versus earth.
该电流值受回路对地的接地泄漏电阻限制。
3
Three methods to judge the electric leakage of flange are put forward, that is, current direction method, pipeline current method and earth resistance method.
