非线性负载会形成非正弦电流，如方波，其中包含谐波成分。
The nonlinear load will draw a nonsinusoidal current, such as a square wave, which contains harmonic components.
例如，电弧炉就是一种非线性负荷，因为加上正弦电压后，它将形成非正弦电流(大量谐波)。
For example, an arc furnace is nonlinear since it will draw a no sinusoidal current (rich in harmonic's) when a sinusoidal voltage is applied.
由功率四边形进一步确立了非正弦交流电路中的电流四边形和导纳四边形，以及它们和功率四边形的相似关系。
Further, the current quadrilateral and admittance quadrilateral, as well as their similarity to the power quadrilateral in non-sinusoidal alternating-current circuits were derived.
