1. What is the Coincidence Factor?

The Coincidence Factor is defined as the fractions of the connected (or rated) load based on actual lighting Watts, motor nameplate horsepower and efficiency. It represents the inverse relationship with the Diversity Factor in electrical system analysis.

2. How Does the Calculator Work?

The calculator uses the Coincidence Factor formula:

Where:

• \( CIF \) — Coincidence Factor
• \( Diversity Factor \) — Ratio of sum of maximum demands to coincident maximum demand

Explanation: The Coincidence Factor represents the probability that different loads will operate simultaneously and is inversely proportional to the Diversity Factor.

3. Importance of Coincidence Factor Calculation

Details: Accurate Coincidence Factor calculation is crucial for proper electrical system design, load forecasting, and determining the actual maximum demand on power systems.

4. Using the Calculator

Tips: Enter the Diversity Factor value (must be greater than 0). The calculator will compute the corresponding Coincidence Factor.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between Coincidence Factor and Diversity Factor?
A: Coincidence Factor is the mathematical inverse of Diversity Factor (CIF = 1/DF).

Q2: What are typical values for Coincidence Factor?
A: Coincidence Factor values typically range from 0 to 1, with higher values indicating greater likelihood of simultaneous operation of loads.

Q3: How is Diversity Factor determined?
A: Diversity Factor is calculated as the ratio of the sum of individual maximum demands to the system's coincident maximum demand.

Q4: What applications use Coincidence Factor?
A: Electrical engineering, power system design, load management, and energy consumption forecasting.

Q5: Can Coincidence Factor be greater than 1?
A: No, since Diversity Factor is always ≥1, Coincidence Factor will always be ≤1.
