Demand factor

In telecommunication, electronics and the electrical power industry, the term demand factor is used to refer to the fractional amount of some quantity being used relative to the maximum amount that could be used by the same system. The demand factor is always less than or equal to one. As the amount of demand is a time dependent quantity so is the demand factor.

${\displaystyle f_{Demand}({\it {{t})={\frac {\text{Demand}}{\text{Maximum possible demand}}}}}}$

The demand factor is often implicitly averaged over time when the time period of demand is understood by the context.

In electrical engineering the demand factor is taken as a time independent quantity where the numerator is taken as the maximum demand in the specified time period instead of the averaged or instantaneous demand. the possible

${\displaystyle f_{Demand}={\frac {\text{Maximum load in given time period}}{\text{Maximum possible load}}}}$
