Analyzing the power quality / switcher power supplies causing harmonics

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 .

Elnet PQ Pass certificate2
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:

Monitoring and control Leakage Current with ELNet LTP Power-meter

 

Control Applications, which set a new high standard in precise electrical metering (1600 samples per cycle), has recently unveiled an advanced multi-meter which allows the monitoring of earth leakage current in an electric panel, alongside with all other standard measured parameters of voltage, current, frequency, power-factor ,energy harmonics etc., all accessible through a user-friendly menu, in high resolution color graphics.

Leakagecurrent-2

Checking Leakage current is your best indication of safety check of your electric facility. A facility, in which a high leakage current was measured beyond what is permitted by regulations, requires a thorough inspection.

Using the ELNet LTP utilizing the power-meter function normally present in electric panel, it is possible to constantly monitor the leakage current in an electric panel, locating the source and magnitude of the leakage at relative ease.

Old version leakage current devices usually performed which all power lines involved are passing through big current transformer, which feature with inaccurate output (inaccuracy up to 15%). These old version leakage current detectors do not provide additional measurements as those mentioned above (V; I; P, PF etc.) and tend to be more expensive than the ELNet LTP solution which includes in it all measureable parameters, including earth leakage current.

New model Elnet VP

Have you ever thought about to have a basic electrical voltage/current measuring device that would replace old “old – school” mechanical meters?

Well, the Elnet VP is that meter.

Elnet VP

It was designed to replace mechanical meters. It can be set up to display either Voltage or Current. The display can also alternate between Voltage and Current every 2 seconds.
