Maximum Demand Formula:
| From: | To: |
Maximum Demand is defined as the peak power consumption of the load connected. The Demand Factor is the ratio of maximum demand to connected load, helping to determine the actual power requirement versus the total connected capacity.
The calculator uses the Maximum Demand formula:
Where:
Explanation: This formula calculates the actual maximum power demand by applying the demand factor to the total connected load, accounting for diversity in usage patterns.
Details: Accurate maximum demand calculation is crucial for proper electrical system design, transformer sizing, circuit protection, and energy management. It helps prevent overloading while optimizing equipment capacity.
Tips: Enter the demand factor (value between 0 and 1) and the connected load in watts. Both values must be positive numbers for accurate calculation.
Q1: What is a typical demand factor value?
A: Demand factor values vary by application but typically range from 0.5 to 0.9 for most electrical systems, depending on the diversity of loads.
Q2: How is demand factor different from diversity factor?
A: Demand factor is the ratio of maximum demand to connected load, while diversity factor is the ratio of the sum of individual maximum demands to the maximum demand of the whole system.
Q3: Why is maximum demand important for utility companies?
A: Utility companies use maximum demand to determine billing rates, plan infrastructure capacity, and ensure reliable power delivery to all customers.
Q4: Can demand factor be greater than 1?
A: No, demand factor cannot exceed 1 as it represents the fraction of connected load that constitutes the maximum demand.
Q5: How often should maximum demand be calculated?
A: Maximum demand should be recalculated whenever there are significant changes to the electrical load configuration or usage patterns.
