Researchers in Malaysia have published a study of total harmonic distortion (THD) reduction techniques in PV systems and claim to have found an holistic and systematic approach. The paper Advances in ...

Coming to grips with the semantics and vocabulary that apply to “distortion” takes a little discipline, but it isn’t all that intimidating. All you need is a little patience to go over the relevant ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

A network of sensors has begun providing what may be the first collection of utility customer readings of one critical measure of power quality reaching U.S. homes. Some 1-million plug-in devices ...

Arteche PQ, Inc. has introduced a complete range of active harmonic filters. This new filter product line achieves 5% total harmonic current distortion (THD) by monitoring the flow of harmonic ...

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 ...

Many continuous-conduction-mode PFC controllers use a nonisolated boost topology with average current-mode control. Examples of such controllers are the UC1852, UC1854/UC1854A/UC1854B family and the ...

Harmonic is one of the most important concepts on the power system that cannot be neglected since it can affect the power quality and operation of equipment. High levels of Harmonics in the system may ...

Tektronix must have been quite a place to work back in the 1980s. The company offered a bewildering selection of test equipment, and while the digital age was creeping in, much of their gear was still ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...
