This paper is preliminary study with focused on the harmonics generated by household appliances. There are only several household appliances that considered in this paper are television set, laptop computer and compact fluorescent lamp (CFL). To measure the input current, the measurement equipment was installed at the input side of equipment under the test. The important parameters that have been recorded are individual harmonic currents, total harmonics distortion, power factor, input current and input voltage wave form. From the measurement results, television sets, laptop computers and CFLs have been found generate the THD_i of 177%, 273.66% and 154.2% respectively. If it is widely used in residential areas, it is likely that there will be increased harmonic distortion in the electric power distribution system. Because this research is still in its early stages, at the end of this research it will be known how much harmonics is generated by the load in the residential area. If amount of harmonics generated by the housing load that exceeds the limit, so the next step of this research a harmonics filter design will carried out.

本文是针对家用电器产生的谐波的初步研究。本文只考虑了几种家用电器，即电视机、笔记本电脑和紧凑型荧光灯（CFL）。为了测量输入电流，测量设备安装在被测设备的输入侧。已记录的重要参数是单个谐波电流、总谐波失真、功率因数、输入电流和输入电压波形。根据测量结果，已发现电视机、笔记本电脑和 CFL 会产生 THD _i分别为 177%、273.66% 和 154.2%。如果在居民区广泛使用，很可能会增加配电系统的谐波失真。由于这项研究仍处于早期阶段，因此在本研究结束时将知道住宅区负载产生了多少谐波。如果外壳负载产生的谐波量超过限制，那么本研究的下一步将进行谐波滤波器设计。
