| 摘 要： | 介绍了发电机三次谐波零序电压的测量结果进行了分析，提出了发电机出口侧主变压器和ＴＰ对机端的三次谐波零序电压有助增的影响，同时证实了中性点经高电阻接地方式下，中性点侧的三次谐波零序电压会下降。为此，建议对发电机三次谐波零序电压定子接地保护应根据现场实际测量结果来对其动作定值进行整定。

| Abstract: | This paper introduces and analyzes the 3ed harmonic voltages measured on generators.The transfonro' and PT will increase the 3hi harmonic voltage at the terminal of generator, and the high resistance connected to the neutral point will decrease 3 harmonic voltage on it was testified through the test .Some suggestions are given to the stator-ground fault protective relays based on the third harmonic voltages. |
