Demand factor is defined as the ratio of maximum demand to the connected load.
Example 1: The MD at a certain system is 18 MW, whereas the connected load is 25 MW. Determine the DF.
Solution: DF = 18 MW / 25 MW = 0.72
Example 2: The electrical load (connected) at a certain power station is known to be 3 MW. The DF is 0.7. Find the MD.
Solution: MD = DF * Connected load = 50 MW * 0.7 = 35 MW
Example 3: The CL at a certain station is 10 MW. The DF is known to be 0.8. Determined the load that is joined.
Solution: CL = MD / DF = 10 MW / 0.8 = 12.5 MW
