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 ...

Portable generators have become an essential power solution in modern life. From residential backup power and outdoor activities to construction sites, mobile businesses, and remote operations, they ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

The power quality industry has developed certain index values that help us assess the quality of service as it relates to distortion caused by the presence of harmonics. These values, or harmonic ...

This application note presents a total harmonic distortion (THD) test circuit that uses active noise amplification to eliminate the need for expensive and often ineffective external filters. Abstract: ...

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 ...

Designing total-harmonic-distortion (THD) measurement into a system usually involves a notch filter and a broadband ac measurement. The problem with this technique is that it measures both THD and ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...

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 ...
