摘要
本文根据对大型电力变压器绕组的传输特性的实验研究，提出了应用于大型电力变压器局部放电在线监测中的多端调节－定向耦合差动平衡消除干扰的新方法，建立了相应的电路模型，在理论上进行了详细的分析，并用实验数据证明了该方法的正确性和实用性。
According to the testing result about transmitting characteristics of windings in large capacity transformer,this paper described a new kind of method,multi adjustment and directional difference balance to supperss interference in on line PD monitoring.Furthermore,this paper established the relevant circuit model and made theoretic analysis in detail.At last,the testing data confirmde that the method was proper and practicable.
