Neutral Current Neutral current is the current that flows in the neutral leg of a paralleling system. Often, this term is used in reference to circulating currents or cross currents.
零线电流 零线电流指的是通过并联系统零线的电流，在谈及环流电流或者交叉电流时常会提到这个术语。

Nonlinear Load A nonlinear load is a load for which the relationship between voltage and current is not a linear function. Some common nonlinear loads are fluorescent lighting, SCR motor starters and UPS systems. Nonlinear loads cause abnormal conductor heating and voltage distortion.
非线性负载 电压和电流之间是非线性关系的负载称为非性形负载。一些常见的非线性负载有荧光灯、可控硅电动机启动器以及UPS系统。非线性负载能导致反常的导体发热和电压畸变。
