摘要
电子式电压互感器(EVT)是智能变电站的关键设备。通过分析比较各种电子式电压互感器的原理及优缺点,结合光学电流互感器发展趋势,提出了一种基于FOCT检测电容电流的新型EVT,弥补了先前各种EVT的不足,是一种很有推广前景的新型电子式电压互感器。
The electronic voltage transformers （EVT） is the key equipment to intelligent substation. Through analyzing and com- paring the principle, advantages and disadvantages of the various electronic voltage transformers, combining with the development trends of optical current transformer, presents a new type of EVT for capacitive current detection based on FOCT. The new EVT makes up the various lack of previous EVT, and is of very promising promotion.
