互感器现场高压介损测量方法的实现

摘要

The connection in series resonance opposition method used to measure high-voltage mutual inductor dielectric loss is an available approach to solve many onsite problems. The different properties between reactance and capacitive reactance were used, so that the connection in series resonance opposition method could reduce the capacity of testing power supply. Experiments verified the feasibility of this method. According to the situation of measured equipment, the onsite connection in series resonance opposition method needed reasonable selection of apparatus and the number of reactors to meet the requirements of testing circuits.%串联谐振补偿法用于互感器高压介损测量是解决现场诸多问题的有效方法。利用电抗与容抗的不同性质，串联谐振补偿法可以大大减小试验电源的容量，给出了测试实例，验证了该方法的可行性。在现场使用串联谐振补偿法进行测量要根据被测设备情况合理选择仪器设备和电抗器台数，使其满足试验回路的要求。
