Harmonics/Harmonic Distortion

There has been much discussion and interest in recent years about the subject of power quality. In the past, power received from the power grid and used by consumers was described as ‘clean power’, meaning that it had a pure sinusoidal wave form.

Peak Load Demand

Peak load demand in an electricity system is the total amount of electricity required by all power consuming devices at the time when demand for electricity is highest. Peak demand periods are generally at predictable times of the day and are usually quoted as a fixed four hour period. A [...]

Power Factor Control

Power factor is just one important step in the larger Power Quality story. This “factor” is calculated using two components of the power in any alternating current electrical circuit. The two components are ‘real power’ (kilowatts) and ‘apparent power’ (kilovolt amps).
