Demand Factor-Diversity Factor-Utilization Factor-Load Factor
Demand Factor = Maximum demand of a system / Total connected load on the system; Demand factor is always less than one. Example: if a residence having 6000W equipment connected has a maximum demand of 300W,Than demand factor = 6000W / 3300W = 55%. The lower the demand factor, the less system capacity required to serve the connected load.اقرأ أكثر
