| 摘 要： | 基于石英晶体的逆压电效应，研制出一种双模干涉式的电子电压互感器。该互感器利用两个低阶模的干涉原理改善了电压互感器的性能，为消除外界干扰、提高系统的测量精度提供理论根据。实验表明：在．40℃～＋40℃的温度范围内，互感器能达到0.2级的准确度。

| Abstract: | Based on the converse piezoelectric effect of quartz, a novel dual-mode interferometric electronic voltage transformer is presented. The performance of voltage transformer is improved by the two steps models interferometric principle, which offers theoretical bases for removing environment interfere and improving system measure precision. Testing results show that the accurate degree of new transformer is 0.2 levels between -40oC~ 40oC. |
