Diversity factor is the ratio of the sum of the individual maximum demands of the various subdivisions of a system or part of a system to the maximum demand of the whole system or part of the system under consideration. Diversity is usually more than one.

Estimation of actual maximum kVA demand

Definition: Diversity factor is defined as the ratio of the sum of the maximum demands of the various part of a system to the coincident maximum demand of the whole system. The maximum demands of the individual consumers of a group do not occur simultaneously. Thus, there is a diversity in the occurrence of the load. Due to this diverse nature of the load, full load power supply to all the consumers at the same time is not required. F D — diversity factor D i — maximum demand of the load I, irrespective of the time of occurrence.

Diversity Vs. Demand: Don't Be Confused by These Terms

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. 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.
