Demand factor | Demand Factor Formula

For example, an oversized motor 20 kW drives a constant 15 kW load whenever it is ON. The motor demand factor is then 15/20 =0.75= 75 %. Demand Factor is expressed as a percentage (%) or in a ratio (less than 1). Demand factor is always < =1. The lower the demand factor, the less the system capacity required to serve the connected load.
