摘要
分析了二次侧具有两个或以上负载绕组电压互感器的误差 ,推导出电压互感器带实际负载运行时 ,计量绕组的误差计算公式 ,并根据误差公式给出了实际负载误差的测试与计算方法。实际测试结果验证了该方法的正确性。
The error of potential transformer (PT) with two and above secondary load windings is dealt with in this paper. The error computing formulas for the measuring winding of practically loaded PT are derived, based on which the measurement and calculation means for actual burden error are presented. Results of actual measurement show the validity of the proposed method.
