The demand factor is defined as the ratio of maximum demand on the power station to the connected load.
Formula of Demand Factor
Demand Factor = Maximum Demand/Connected Load
Practically the value of maximum demand is smaller than connected load, and thus the demand factor is always less than 1.
Solved Examples and Calculations
Example#1: Calculate the demand factor when the maximum demand of 5 kW connected load is 3.8 kW.
Demand factor = 3.8/5 = 0.76
Also learn about Load Factor Formula
Example#2: If maximum demand is 84 kW and the connected load is 100 kW, what is the value of the demand factor.
Demand factor = 84/100 = 0.84
