Analyzing the power quality
The use of advanced technologies in today’s electrical products has a negative impact on the quality of electrical power supplied to the consumers. The root of the problem lies in the massive use of “switching power suppliers” in variety of electrical products such as LED-based lightning fixtures, computers, screens, printers, Industrial energy consumers such as variable-speed drive (VSDs) and more.
Switching power suppliers used in the industry, commercial buildings and private sector affects the quality of the power supply by creating harmonies and distortions on the electrical grid, resulting in large number of cases damage to the electrical grid, electrical panels and damage to the electrical products connected to the electrical grid.
In order to overcome this problem, we must use objective measuring tools so that we can measure and know the type of problem and the magnitude of the problem, which is a preliminary and necessary step in solving the problem.
IEC 61000-4-30 standard is designed to determine the accuracy and quality of the measurements done by the analyzer (rate of measurements, method of measurements and accuracy) in order to get an objective measuring tool .
Control Applications Ltd. ElNet PQ tested and found to be suitable by an accredited laboratory (the American PSL) in this standard as a Class A certified electrical quality measurement analyzer.
The Utility companies have set relatively easy statistical standards to test the power quality, which relies heavily on average and statistical data this standard defined as the EN50160 standard and provided as part of the UniWeb software provided by a Control Application Ltd. as a power quality monitoring software.
The best solution for EN50160 reports is the Elnet PQ:
