Power System Utilization
Diversity Factor (Definition)
DvF = \Sigma(Individual\ Max\ Demands) / System\ Max\ Demand
Variables
| DvF | Diversity factor | - |
| ΣIndividual | Sum of each sub-system's individual peak | kW |
| SystemMax | Actual coincident system peak | kW |
Engineering Example
Three feeders peaking at 50, 40, and 30 kW individually (sum 120 kW) but only 90 kW coincident: DvF = 120/90 ≈ 1.33.
Practical Site Example
This is exactly the factor used in the Maximum Demand calculator — a DvF above 1 means peaks don't all happen together.
