The principle, testing of generator stator ground protection based on the third harmonics, measurement of the third harmonics on generator stator are introduced.
介绍了漫湾电厂发电机3ω定子接地保护原理、调试方法及发电机定子三次谐波电压的测试。
Through cooperating each other between the generator stator ground protection, it can operate sensitively when single phase ground fault in whole range of generator stator winding occurs.
通过发电机定子接地保护之间的相互配合，在整个发电机定子绕组范围内发生单相接地故障时，发电机定子接地保护均能灵敏地动作。
Hence, the stator and rotor ground fault protection play an important role in the protection system of generator.
