It is harmful to the characteristics of the transformers on line. It causes the increasing of magnetizing current, harmonics leakage magnetic flux, and thus the losses, which in turn results in the structures overheating and insulation ageing.

电力变压器的磁动势和磁通出现直流分量的现象称为"直流偏磁"，这一现象将对变压器的正常运行产生不利的影响，诸如励磁电流有效值、高次谐波成分及其相应损耗的增加，铁心高度饱和引起的漏磁通的增加，以及由此引发的局部过热、绝缘老化等问题。

Because the magnetoelectricity characteristic of TA is not linear, huge short-circuit current or large nonperiodic current may make the TA enter the saturated state, which cause the exportation current of the TA very small, making the busbar differential current very large.

母线区外故障时，由于带铁心TA 激磁电感的非线性特性，强大的短路电流及较大的非周期分量都可能使TA 进入深度饱和状态，此时TA 的励磁阻抗将变得很小，一次电流大部分流入励磁支路，导致TA 输出电流很小，使得母线保护差动电流很大，如果不采取一定的措施，极易发生误动。
