negative phase sequence current

The unbalanced degrees of current in primary winding under different load conditions are discussed, which are based on the general expressions of negative phase sequence current.

结合负序电流的通用表达式，讨论了在不同负荷条件下的原边电流不平衡度。

Zero-sequence current criterion, negative sequence current criterion and phase current variation can be used to improve the performance of breaker failure protection for ACF sub-bank.

针对单纯采用相电流判据的不足之处，本文提出增加零序电流、负序电流及电流变化量判据，以有效地避免保护误动或者拒动。

Experimental results prove the proposed control method can compensate the harmonic, negative sequence and zero sequence current components in the three phase four wire.

实验结果表明，该装置可对三相四线制系统中的谐波、负序、零序等电流分量进行补偿。
