Chapter three mostly discusses the detection of neutral harmonic current and control strategy in two ways.

第三章主要讨论中性线谐波电流的检测和补偿控制策略两个方面。

This is particularly the case for the third harmonic, which causes a sharp increase in the zero sequence current, and therefore increases the current in the neutral conductor.

尤其是第三个谐波，这将导致零序电流急剧增加，从而增加了中性线的电流。
