摘　　要：分析了实践工作中碰到的10kV两段母线电压互感器一、二次同时并列运行时，当其中一台电压互感器发生高压侧熔丝熔断后两台电压互感器烧毁的原因，并提出改进措施和10kV母线电压互感器并列运行时的一些注意事项。The paper introduced a practice example： two 10 kV potential transformers were both on parallel running, when one of PT＇s high side fuse burn -out, the two devices burned down. The burnt reason were analysed and the improvement measures and some attentions were put forward.
