摘　　要：基于反射式偏振干涉原理和模间干涉原理,研制出一种新型的可同时测量母线上的电流和电压的组合式互感器。这种互感器绝缘结构简单,电压测量与电流测量间无相互干扰,为消除外界干扰、提高系统的测量精度提供了理论根据。Based on the reflect-polarization interferometric electronic current transformer interferometric electronic voltage transformer, a new type combined transformer that can simultaneously measure high voltage and heavy current was developed and tested. This transforner features simple insulation structure and no interference between current measurement and voltage measurement,which provides a theoretical guide for avoiding environment interfere and improving system measurement precision.
