针对佛山电力局500kV罗洞变电站#4主变投运以来，由于运行环境、系统环境等因素的影响，主变噪声水平随着并联电容器组投入组数的增加而明显升高，部分测点在投入一组电容器组后即超过额定最大噪声值。本文针对此现象制定了周密详细的噪声及谐波电流测试方案，结合实测数据和理论分析，找出造成此现象的真正原因。

Since the operation of #4 transformer in 500kV Luodong substation of Fosan power bureau, and due to the influence of operation environment and system conditions, the noise level of transformer increases with the number of operating shunt capacitors. The noise level at some measuring points exceeds the rated max noise even when only one group of capacitor is running. This paper has established elaborate and detailed test schemes for noise and harmonic current, and has found the underlying reason for the issue with measuring data and theoretical analysis.
