When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

• Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in VAR. • Power-factor correction circuits can be either an individual style or of the bank ...

Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...

1. Power-factor triangle relates the real power, the reactive power, and the apparent power. (Courtesy of Vector Group) Let’s start by talking about the concept of power factor (PF). Assuming ...
