Unbalance Analysis for Three Phase Current in Power Ling Caused by Incomplete Transposition

并通过分析平衡牵引变压器补偿前后的牵引母线电流、牵引母线电压，得出三相电流不平衡度、牵引电流总谐波畸变率与补偿度之间的关系。

Through analyzing traction bus current , traction bus voltage before and after compensation , the relationship between three-phase current unbalance degree , traction current total harmonic distortion rate and compensation degree is presented .

对于单相负荷，通常原方三相电流是不平衡的，但通过补偿，也可实现平衡变换。

The single phase load is generally not considered as balance , but its balance transformation can be realized by compensation .

实践证明，这种变压器三相侧电流的不平衡程度可以满足有关规定。

It has been proved in practice that the unbalance degree of the three-phase side current of this transformer can meet the requirements of the related regulations .
