Nonlinear Loads Effect on Harmonics in the Laboratory
The research concentrated primarily on the meter side of customers because it investigated harmonic effects at K.Wai Perlis' Electrical System Engineering School laboratory. Magnetic fields from harmonic voltage frequencies rotate at the same speed as harmonic frequencies but harmonic currents inside equipment result in operational overheat and performance losses. This disruption produces mechanical noises and equipment vibrations which also causes overheating of equipment and operating efficiency reduction as well as voltage stress against insulation of equipment windings. The research employs Computers and Printers as well as Air Conditioners and Compact Fluorescent Lamps as harmonic-significant loads. The measurement process depends on the Fluke 435 Power Quality Analyzer. The harmonic current parameters fluctuate unpredictably due to the installation of different nonlinear loads. Through this research study the utility obtains substantial knowledge about harmonic effects on their equipment. The utility will gain knowledge about the expenses and performance losses which result from using these pieces of equipment. This paper presents information about harmonic investigation expenses through THD measurement as well as energy loss costs.
