摘　　要：文中通过对大型自耦变压器投运过程中,变压器高、中压侧单独带低压侧电容器组运行时,公共绕组及低压侧套管电流的幅值、相位进行分析,并例举了某变电站自耦变压器投产时公共绕组及低压侧套管电流幅值及相位的计算过程,对投运现场发生故障时的分析及继电保护作业人员具有分析及指导意义。This paper analyzes the amplitude and phase of the common winding and the bushing current of the low-voltage side when the high-and medium-voltage sides of the transformer are operated with low-voltage side capacitor banks during the operation of large autotransformers.The calculation process of the current amplitude and phase of the common winding and the low-voltage side bushing when the coupled transformer is put into production has analysis and guidance significance for the analysis of the failure at the commissioning site and the relay protection operators.
