摘　　要：根据大型汽轮发电机上的轴电压实测经验,分析认为在发电机静态励磁系统内安装的轴电压滤波器对发电机轴电压抑制作用不大,建议在发电机轴颈处安装抑制器,并确保发电机汽端可靠接地。By the test experience of shaft voltage measurement on large steam-turbine generators,it conclude that the Shaft Voltage Filter,which is equipped between field circuit and ground in static excitation system,of which effectiveness for generator shaft voltage is not ideal,it is recommended to install the suppressor at the generator journal and ensure that the generator turbine end reliably grounding.
