Understanding arc flash incident energy is crucial for electrical safety in industrial environments. This energy can significantly impact safety measures and protective equipment requirements. Our calculator provides a straightforward way to determine the arc flash incident energy based on the given parameters.
Formula
The arc flash incident energy (E) is calculated using the formula: E = (B / D)², where B is the incident energy and D is the distance.
How to Use
- Enter the incident energy value in the “Incident Energy” field.
- Enter the distance value in the “Distance” field.
- Click the “Calculate” button to get the arc flash energy.
Example
If the incident energy is 100 and the distance is 5, entering these values into the calculator will show the arc flash energy based on the formula provided.
