三相电流互感器带负荷相量测量结果分析

Analysis of the Phasor Measurement Results on Three-phase TA with Load

利用相量法,对电流互感器完全星形接线在二次回路接线有误时的各种相量测量结果进行分析,得出U、V、W、N相电流的相角差和幅值大小。该成果有助于对现场电流互感器二次回路的接线情况进行更快更准确的判断。

Using phasor method to analysis the phasor measurement results when the secondary loop of TA complete star connection has a variety of errors,we can conclude the phase angle difference and the amplitude of U、V、W、N phase current.The results contribute to faster and more accurately determine the field current transformer secondary circuit wiring.
