1·The elevated terminal D' connects with the centre of the coil A' and the other terminal is connected to earth and preferably, also, to the coil C' again for safety reasons as mentioned above.

高处的终端D'连接线圈的A'中心，其它终端更适宜连接地线，同样，对于线圈C'在此之上鉴于安全再次提醒。

2·In coordination with the application of post-set arc suppression coil, a frequency scanning based modified method for detecting system capacitance to earth is proposed.

为配合随调式消弧线圈的使用，提出了一种扫频检测系统对地电容的改进型方法。

3·Then it introduces the rotor earth fault monitoring based on the method of resistance bridge with source, and the interturn short circuit fault monitoring in generator rotor based on stator coil.

随后介绍采用基于有源电阻电桥进行转子接地短路故障监测与采用微分探测法进行转子匝间短路故障信号。
