| 摘 要： | 基于工程实例分析了主变压器高低压侧电流不平衡故障现象。现场实测与理论分析表明,这种故障的出现由供电和用电过程中产生的谐波导致,致使三相电流的夹角产生较大偏移。由此认为,确保动态无功补偿设备的质量可以有效消除这种故障的出现。

| Abstract: | Current imbalance faults on the high-low voltage side of the main transformer were analysed based on practical engineering cases.Field measurement and theoretical analysis show that the fault results from large angle offset of the three-phase current caused by the harmonics generated in the process of power supply and power consumption.A solution to the faults is to ensure the quality of dynamic static var compensation devices. |

| Keywords: | transformer current static var compensation fault power grid |
