本文介绍了一组测量结果，用于研究由于引入节能灯（CFL 和 LED 灯）而导致国内客户谐波发射的变化。已通过幅度和复杂谐波电流研究了这种发射。我们可以看到发射取决于作为背景连接的灯。有时添加新设备会减少谐波，有时会增加谐波。总负载产生的谐波电流明显小于各负载单独产生的谐波电流的代数和。因此，不仅在设备之间，而且在客户之间也可能产生某种抵消效应。总体而言，测量结果证实了这样的结论：由于用 CFL 和 LED 灯替代白炽灯，谐波发射有所增加，但没有理由担心。
This paper presents the results of a set of measurements to study changes in harmonic emission from a domestic customer due to the introduction of energy-efficient lamps (CFL and LED lamps). This emission has been studied through both magnitude and complex harmonic current. We can see that the emission depends on the lamps that are connected as a background. Sometimes adding a new device reduces the harmonic sometimes it increases it. The harmonic current produced by aggregate loads is significantly smaller than the algebraic sum of the harmonic current produced by each one separately. Therefore, it can be some cancellation effect not only between devices, but also among customers. Overall, the measurements confirm the conclusion that there is some increase in harmonic emission due to the replacement of incandescent lamps by CFLs and LED lamps, but that there is no reason for concern.
