Harmonics of the 60 Hz power frequency has been around for a long time. It was observed on transmission systems in the early 1890s and was associated with voltage and current waveforms. As equipment ...

This FAQ provides a technical overview of harmonics, their primary sources, and the industry standards established for their control.

Yokogawa's LS3300 Precision AC Power Calibrator now comes with the added option of Harmonic Output Capability.

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...

With the rising demand of non-linear type equipment and loads, mitigation of harmonics becomes increasingly important. If a harmonics study or testing indicates excessive harmonic levels or a ...

Editor’s Note: Harmonic voltages in the power supply can raise the temperature of electrical equipment and therefore inhibit performance. As a result of the increased application of high-speed ...
