摘要(Abstract)：

分析了发电机出口电压互感器(TV)断线引起励磁故障异常跳机的案例,指出主要原因是高压熔丝性能劣化,二次电压缓慢跌落,励磁调节器未能自动切换至备用通道所致,提出了切实可行的解决方案。
Through the analysis on the case of abnormal tripping for the excitation fault caused by the disconnection of generator terminal TV,this paper identifies the reason as high-voltage fuse performance degradation,slow drop of secondary voltage and excitation regulator failing to automatically switch to standby channel.In addition,it presents the feasible solution.
