1. What is Diversity Factor?

Diversity Factor (DF) is a ratio used in electrical engineering that compares the sum of individual maximum demands to the maximum total demand of a system. It indicates how much the peak demands of individual loads occur at different times.

2. How Does the Calculator Work?

The calculator uses the Diversity Factor formula:

\[ DF = \frac{\text{Sum of Individual Max Demands}}{\text{Max Total Demand}} \]

Where:

\( DF \) — Diversity Factor (dimensionless)
\( \text{Sum of Individual Max Demands} \) — Total of maximum demands from all individual loads (kW)
\( \text{Max Total Demand} \) — Maximum simultaneous demand of the entire system (kW)

Explanation: A higher diversity factor indicates that individual loads peak at different times, allowing for more efficient system design with lower capacity requirements.

3. Importance of Diversity Factor Calculation

Details: Proper calculation of diversity factor is essential for designing electrical systems, determining transformer sizes, calculating cable capacities, and optimizing infrastructure costs in residential, commercial, and industrial applications.

4. Using the Calculator

Tips: Enter the sum of individual maximum demands and the maximum total demand in kilowatts (kW). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical diversity factor value?
A: Diversity factor typically ranges from 1.0 to 3.0 or higher, with values above 1.0 indicating that individual loads don't peak simultaneously.

Q2: How does diversity factor affect system design?
A: Higher diversity factors allow for smaller, more cost-effective system components since the maximum simultaneous demand is lower than the sum of individual maximum demands.

Q3: What's the difference between diversity factor and demand factor?
A: Diversity factor compares sum of individual maxima to system maximum, while demand factor compares maximum demand to connected load.

Q4: When is diversity factor most important?
A: It's crucial in residential and commercial building design, industrial plant electrical systems, and utility distribution planning.

Q5: Can diversity factor be less than 1?
A: No, diversity factor is always greater than or equal to 1, since the sum of individual maximum demands cannot be less than the maximum total demand.
