In addition, it is also of extreme importance to mitigate these harmonic distortions using new techniques. Thus, this paper is considering the Air Conditioners (ACs) load; which is a particularly swiftly escalating load, with nonlinearity, in hot areas and this results in harmonics contaminations.
Harmonic distortion caused by increasing non-linear loads can result in issues in a building's electrical system. This newsletter provides a simplified explanation of the causes of harmonic distortion by taking the reader through some electrical system basics and moving on to what harmonic distortion means and why it matters.
From minor control trips to compressor and transformer failures, harmonics can impact every type of HVAC equipment. A technician recently docu-mented the fault codes received when a chiller circuit tripped. A close look at the chiller revealed that the indicated faults did not match up to what was going on with the unit.
Conclusions Integration of inverter connected PV and wind power plants, and rampant rise in nonlinear loads have led to harmonic problem in power system. Devices with nonlinear voltage and current relationships include iron core reactors and arcing appliances such as generators, transformers, motors and arc furnaces.
From a building owner’s perspective it can be difficult to predict the impact of harmonics on the electrical components and equipment in the building. All buildings contain non-linear electric loads that are generating harmonic distortion but few buildings suffer any ill effects.
