Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

As a solid state light source, light-emitting diodes (LEDs) have been widely used due to their superior longevity, excellent efficacy, and friendly environmental attributes. Today, LEDs are replacing ...

We've all been taught that power factor (PF) is the ratio of real power to apparent power, or the cosine of the phase angle between sinusoidal current and voltage waveforms. When the current isn't ...

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 ...
