Abstract

Experimental data are presented on the effect geomagnetically induced currents have on a power transformer. An analytical solution is obtained for current harmonics via nonlinear inductance under dc bias. It is shown that the nonmonotonic dependence of the harmonic amplitude on the dc value is determined by the nonlinearity of the weber–ampere characteristic of inductor.

地磁感应电流对电力变压器谐波的影响

摘要

实验数据介绍了地磁感应电流对电力变压器的影响。通过直流偏置下的非线性电感获得了电流谐波的解析解。结果表明，谐波幅度对直流值的非单调依赖性是由电感的韦伯-安培特性的非线性决定的。
