两相TA带负荷相量测量结果分析

Analysis of Phase Measurement Results of Two-phase TA with Load

分析TA不完全星形接线二次回路发生各种接线错误时的相量测量结果。运用相量分析法,推导出TA不完全星形接线二次回路A相、C相、N相电流之间的相角差和幅值相对大小。分析结果有助于快速、准确地判断现场TA二次回路的接线情况。

Phase measurement results under every incorrect connections of secondary circuit of TA incomplete star connection are analyzed. By using phase analysis method, Phase difference and relative amplitude between phase A, B and C of secondary circuit of TA incomplete star connection are deduced. The analysis results is helpful to judge quickly and correctly the field connection of TA secondary circuit.
