But certain loads in a power system produce voltages and currents with frequencies that are integer multiples of the 50 or 60 Hz fundamental frequency. \u00a0Power system harmonics are these higher frequencies that a form of electrical pollution.<\/p><p>Power system harmonics are not a new phenomenon. Converters and transformers that used in electrical power systems produce harmonic distortion current that inductively coupled into adjacent communication line and produce audible channel interference.<\/p><p>The ideal power system supply is a pure sinusoidal waveform. This pure sinusoidal form of the supply waveform can be distorted due to the presence of harmonics.<\/p><p>Care Labs offers several professional electrical safety testing and inspection services to companies in Mexico. We provide comprehensive harmonic analysis service for all types of facilities.<\/p><h2><strong>What are Harmonics?<\/strong><\/h2><p>Harmonic distortion is one of the very important phenomena in the electrical power system that can\u2019t be neglected since this distortion can affect the quality of power and equipment operation. Harmonic pollution distorts current\/ voltage waveform, disturbing the power distribution system and distort the power quality.<\/p><p>High levels of Harmonics present in a system may leads to number of consequences like overheating effect, the shorten the life of the equipment, reduce the overall power factor.<\/p><p>Basically, harmonic distortions are caused by non-linear loads in the system. Rectifiers, converters, uninterruptible power supply, and variable frequency drives are examples for non-linear loads &amp; source of harmonics and distort the voltage and current waveform.<\/p><p>Nonlinear loads alter the ideal sinusoidal waveform nature of the power supply. Then consequently drop the voltage, which results the flow of harmonic currents in the power system that can cause communication circuits interference and other equipment.<\/p><h2><strong>Effects of <\/strong><strong>Harmonics:<\/strong><\/h2><p>The observed harmonic effects are<\/p><ul><li>Increased losses<\/li><li>Malfunction of meters and power system equipment<\/li><li>Additional neutral current<\/li><li>Inefficient power consumption<\/li><li>Increased possibility of harmonic disturbance amplification due to series and parallel resonance.<\/li><li>Aging of Insulation<\/li><\/ul><p>To prevent technical and economic costs, <a href=\"https:\/\/carelabz.com\/mx\/blog\/why-is-harmonic-study-and-analysis-important-for-companies-in-mexico\/\">harmonic analysis<\/a> for power system can be employed. Harmonic analysis is an arithmetical analysis method of predicting potential risks due to harmonic presence in a system.\u00a0<\/p><p>It also offers the means of evaluating all appropriate solutions and determine their effectiveness under various conditions before implementation.\u00a0<\/p><h2><strong>Total Harmonic Distortion <\/strong><strong>(THD):<\/strong>\u00a0<\/h2><p>THD is defined as the measure of the harmonic pollution present in a supply wave. Power quality of an electrical system is inversely proportional to THD. More harmonic distortions in the power system, the lower will be the quality of power quality and vice versa.<\/p><p>The Total Harmonic Distortion is equal to the ratio of the RMS value of harmonic content to the fundamental value:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7e02eca elementor-widget elementor-widget-image\" data-id=\"7e02eca\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"http:\/\/bangaloreflats.in\/mexico\/wp-content\/uploads\/2021\/09\/Har.png\" title=\"\" alt=\"Harmonic Analysis for Power System in Mexico | Care Labs\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dd6eae0 elementor-widget elementor-widget-text-editor\" data-id=\"dd6eae0\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>here V<sub>n-rms<\/sub>\u00a0&#8211; nth harmonic distortion RMS voltage in the supply signal<\/p><p>\u00a0V<sub>fund-rms<\/sub>\u00a0&#8211; RMS voltage with the fundamental frequency.<\/p><h2><strong>Approach and Methodology:<\/strong><\/h2><ul><li>The first thing is we model of your entire electrical system\/network as a single-line diagram to perform harmonic distortion analysis and set all the parameters to the system components.<\/li><li>Emphasize given more on the facility system buses that are likely to be affected by harmonic disturbances and the point of common coupling (PCC) that connects the facility network to the utility or the adjacent network.<\/li><li>Collect the harmonic disturbance data of all connected nonlinear loads within the facility and verify the accepted limits on current and voltage harmonics.<\/li><li>Care Labs is an authorized service provider of ETAP.
