The leakage current can be determined by applying a known voltage and measuring the current between either path to ground or path to path.
通过施加一个已知的电压，然后测量通路至地或通路至通路的电流，即可确定漏泄电流。
Leakage current can be determined from path to ground or from path to path.
可以确定通路至地、通路至通路的漏泄电流。
Research purposes: By researching and developing differential current transducer used for leakage detecting, to adapt the ground protection of traction inverter in localization type a metro vehicle.
研究目的：研制开发用于漏电检测的差动电流传感器，以适应国产化a型地铁车辆的牵引逆变器接地保护的要求。
