Demand Factor Calculator

What is Demand Factor?

Demand Factor is a measure used in electrical engineering to express the ratio of the maximum demand to the connected load of a system. It is an important parameter in electrical load calculations and system design.

How to Use This Calculator

1. Enter the Connected Load in kilowatts (kW). This is the total power rating of all equipment connected to the system.
2. Enter the Maximum Demand in kilowatts (kW). This is the highest power demand recorded over a specific period.
3. Click the Calculate button to compute the Demand Factor.
4. The result will be displayed as a decimal number representing the Demand Factor.

Interpreting the Results

The Demand Factor is typically less than 1. A lower Demand Factor indicates that the system is using its connected load more efficiently, while a higher Demand Factor suggests that the system may need to be resized or additional capacity may be required.

Formula

Demand Factor = Maximum Demand / Connected Load

Example

If a building has a connected load of 500 kW and a maximum demand of 350 kW, the Demand Factor would be:

Demand Factor = 350 kW / 500 kW = 0.7
