The proliferation of end-use electrical and electronic loads in customer facilities — residential, commercial, and industrial — is not slowing down. Despite economic pressures, utility customers are ...

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 ...

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 ...

Power quality and harmonics have been a developing and growing concern as buildings have become more reliant on technology, the ever-increasing utilisation of digital control systems, and the drive ...

Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also ...

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior ...
