But the parasitic capacitance existed in GIS bus line will append lots of condensive load in the rated voltage, so when testing the GIS bus line voltage transformer, the booster is not allowed. 但在测试GIS母线电压互感器时,由于GIS母线存在的寄生电容在额定电压下将附加大量的容性负载,因此不允许使用试品升压。
In this paper, the author introduced the fixed value setting of underexcited limitation in ABB excitation system. And also analyzed the condensive operation of No. 1 generating unit. 介绍ABB公司励磁系统低励限制的定值整定,分析北京热电分公司1号发电机进相运行时的动作情况以及ABB励磁系统低励限制与失磁保护之间的关系。
