摘要
针对锦屏二级水电站发电机中性点CT匝间短路故障现象,结合中性点CT的布置结构,分析邻近设备高温对CT运行的影响,为发电机中性点CT的故障分析判断提供处理办法。
There was an incident on turn-to-turn short- circuit fault of hydraulic generator neutral point CT. According to structure of neutral point CT, the paper analyses effect of high temperature of nearby equipments for CT working. This method can be used for reference in the fault analysis and treatment of generator neutral point CT.
