Non-linear Loads
A non-linear load on a power system is typically a rectifier (such as used in a power supply), or some kind of arc discharge device such as a fluorescent lamp, electric welding machine, or arc furnace. Because current in these systems is interrupted by a switching action, the current contains frequency components that are multiples of the power system frequency. Distortion power factor is a measure of how much the harmonic distortion of a load current decreases the average power transferred to the load.

Famous quotes containing the word loads:
“The bookful blockhead, ignorantly read,
With loads of learned lumber in his head.
With his own tongue still edifies his ears,
And always listening to himself appears.”
—Alexander Pope (1688–1744)
