1. What is Diversity Factor?

Diversity Factor is a ratio used in electrical engineering that represents the relationship between the sum of individual maximum demands and 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:

\[ DF = \frac{\sum Individual\ Max\ Demands}{Max\ Total\ Demand} \]

Where:

\( DF \) — Diversity Factor (dimensionless)
\( \sum Individual\ Max\ Demands \) — Sum of all individual maximum demands in kW
\( Max\ Total\ Demand \) — Maximum total demand of the system in kW

Explanation: A diversity factor greater than 1 indicates that individual loads peak at different times, allowing for more efficient system design.

3. Importance of Diversity Factor

Details: Diversity Factor is crucial for electrical system design, helping engineers determine the appropriate capacity for transformers, feeders, and other electrical equipment while optimizing costs and efficiency.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What does a Diversity Factor of 1.5 mean?
A: A DF of 1.5 means the sum of individual maximum demands is 1.5 times the maximum total demand, indicating good load diversity.

Q2: What are typical Diversity Factor values?
A: Typical values range from 1.0 to 3.0, with residential areas having higher diversity factors (1.5-3.0) and industrial areas having lower ones (1.0-1.5).

Q3: How is Diversity Factor different from Demand Factor?
A: Diversity Factor compares sum of individual peaks to system peak, while Demand Factor compares actual demand to connected load.

Q4: Why is high Diversity Factor desirable?
A: Higher diversity factors allow for smaller, more cost-effective electrical equipment since not all loads peak simultaneously.

Q5: How does Diversity Factor affect system design?
A: It helps determine the appropriate capacity for transformers, cables, and protection devices, preventing overdesign and reducing costs.
