1. By now, there are four methods of earth: neutral point un-earth, neutral point directly earth, neutral point earth with resistance, neutral earth with an arc suppression coil. 目前主要的接地方式有中性点不接地、中性点直接接地、中性点经电阻接地、中性点经消弧线圈接地。

3. Non-ground neutral system and arc-suppression-coil-ground neutral system are called non-direct ground neutral system. 中性点不接地系统和中性点经消弧线圈接地系统统称为中性点不直接接地系统，广泛应用于铁路配电系统中。
4. Non-ground neutral system and arc-suppression-coil-ground neutral system are called non-direct ground neutral system that is widely used in power distribution system. 中性点不接地系统和中性点经消弧线圈接地系统统称为中性点不直接接地系统，广泛应用于铁路配电系统中。
5. Line-To-Neutral Voltage In a 3-phase, 4-wire, Y-connected generator, line-to-neutral voltage is the voltage between a phase and the common neutral where the three phases are tied together. 相电压在三相四线星形连接的发电机中，相电压是指三相连接点与每相之间的电压。
