摘要
高压计量装置现场接线复杂,错误接线很难判别,且判别中算法复杂,无法快速准确的给出结果。通过现场简单测试电能表各计量元件之间的相位角度,作出各计量元件之间的相量图,通过整体旋转相量图的方式,快速判断出三相三线计量装置在感性负载和容性负载下的接线关系,实现三相三线电能表错接线的快速精确识别。
The result of the error connections can’t be obtained accurately and rapidly because of the complex of connections in the field and the criteria algorithm. The phasor diagram between the measuring components can be easily established according to the angle measured in the field. Wiring relations of inductive load and capacitive load can be determined quickly after the overall rotation of phasor diagram. So error connections of three - phase and three - wire measuring device can be discriminated quickly and accurately.
