摘　　要：电子式电流互感器已经成了国内外研究的热点,其中有源电子式互感器高压侧电路的供能问题则是研究工作中的关键技术。提出了一种用补偿线圈和充电电池相结合的方法对母线电流取能方式进行改进。实验结果表明,该电源能够满足高压侧电子电路的供能要求。Electronic current transformer has been the hot spot of the research at home and abroad, and the current measurement ot active electronic current transformer at high potential side is the key problem in the research. A new method combining compensation coil with rechargeable batteries is proposed to improve the method of taking power from busbar current. The results show that it can satisfy the requirements of the high potential circuit power supply.
