（1）3500/33 Bentley当电压互感器一次或二次稳妥熔断，或回路接触不良，将会出现电压表指示为零或三相电压不平衡，电度表转慢，稳妥熔断，维护宣布“电压回路断线”、 “单相接地”等信号。

（2）应首要经过丈量判别是稳妥熔断仍是单相接地，若发现一次稳妥熔断，应摆开隔离开关摇测电压互感器绝缘，或用万用表检测线圈的完整性，如绝缘杰出时，替换稳妥后投入运行。

（3）3500/33 Bentley 二次稳妥熔断或快速开关跳闸后，若查看二次回路杰出，当即替换稳妥或合上二次快速开关。

（4）若不是稳妥熔断及二次快速开关跳闸，则应查看回路有无断线或接触不良等情况。

（5）3500/33 Bentley当发现电压互感器有漏油、喷油、冒烟、内部有反常声响、严峻发热或火花放电现象时应当即停运。
