One of the most often mentioned and misunderstood power quality issues we see with commercial, industrial, and power-generating electrical equipment is harmonics. Since it’s impossible to explain the ...

This article is part of a multi-part series on how to identify, monitor, diagnose, and deal with harmonics in electrical power systems. Last month’s article discussed how to determine if current ...

Data center operators are keenly aware that securing access to the grid is job number one on their to-do list. But the extraordinary demand placed on the grid by artificial intelligence (AI) and ...

The steady increase in non-linear loads on the power supply network such as, for instance, variable speed motor drives (VSDs), raises questions about power quality and reliability. In this respect, a ...

How to measure harmonics in a power system. Methodologies for reducing power system harmonics. A look at "triplen" harmonics. The IEEE standard 3002.8-2018, “Recommended Practice for Conducting ...

Infrared (IR) thermal imaging (thermography) is an effective troubleshooting tool, but many electricians who use IR cameras to spot overheated wires, connections and components may not be ...

Designed for three-phase power electronics with 6-pulse rectifier front ends — such as ac and dc motor drives — the ECOsineT load-applied passive power quality filters tame harmonic waves. Total ...

Schweitzer Engineering Laboratories, Inc. (SEL) announced that Georgian State Electrosystem (GSE)—the high-voltage transmission system operator for the Republic of Georgia—recently chose to ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

To promote the sustainable-energy transition, an increasing number of photovoltaic rooftop panels and wind turbines are being connected to low-voltage and medium-voltage networks. The integration of ...
