发电机是电力系统的原动力，在运行中必须具备对突发性故障的应变能力，发电机中性点的接地方式与此有密切的关系。发电机中性点的接地方式有：中性点直接接地、中性点经低阻抗接地、中性点不接地、中性点经消弧线圈接地、中性点经高阻抗接地。在热力和电气性能上，能满足电力中性点对设备的要求，具有耐受温度高、电阻率高、电阻温度系数小 。
The generator is the original power of the power system, so it must have the ability to deal with sudden fault in operation. The grounding mode of the generator neutral point is closely related to this. The grounding methods of generator neutral point include: direct grounding of neutral point, low impedance grounding of neutral point, ungrounded neutral point, arc suppression coil grounding of neutral point and high impedance grounding of neutral point. In terms of thermal and electrical performance, it can meet the requirements of power neutral point for equipment, with high resistance temperature, high resistivity and small resistance temperature coefficient.
