1. What is Generator Load?

Generator load is the percentage of a generator's capacity that is being used at a given time. It's calculated by comparing the actual power consumption to the generator's rated capacity.

2. How Does the Calculator Work?

The calculator uses the generator load equation:

Where:

• \( P \) — Actual power consumption (W)
• \( P_{gen} \) — Generator's rated capacity (W)
• \( load \) — Generator load percentage (%)

Explanation: The equation calculates what percentage of the generator's maximum capacity is currently being used.

3. Importance of Load Calculation

Details: Proper load calculation helps prevent generator overload (which can cause damage) and underload (which can lead to inefficient operation and "wet stacking" in diesel generators).

4. Using the Calculator

Tips: Enter the actual power consumption in watts and the generator's rated capacity in watts. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal generator load percentage?
A: Most generators operate most efficiently at 70-80% load. Continuous operation below 30% or above 90% is generally not recommended.

Q2: How often should I check my generator load?
A: Load should be monitored whenever significant changes occur in power demand or when adding/removing equipment.

Q3: What happens if my generator is overloaded?
A: Overloading can cause overheating, reduced lifespan, and potential failure of the generator.

Q4: Can I use this for three-phase generators?
A: Yes, as long as you're using the total power values (sum of all phases) in watts.

Q5: Should I consider power factor in this calculation?
A: This calculator uses real power (W). For apparent power (VA) calculations, power factor would need to be considered.
