Arc Flash

Arc Flash Services

An arc flash is a sudden release of electrical energy through the air, caused by a fault or short circuit. The result can be an explosion of heat, light, and pressure powerful enough to injure workers and destroy equipment. With the right analysis and protection strategies, the risks can be significantly reduced.

1. Data Collections

We start with the details: voltage levels, utility fault current, breaker settings, transformer data, and conductor sizes. Accurate data leads to accurate results.

2. System Modeling

We update or create a one-line diagram and model your system in professional software like SKM Power Tools. This gives us a clear picture of how your electrical system behaves.

3. Short-Circuit Study

We calculate fault currents and check equipment ratings. This helps us spot weak points before they become dangerous.

4. Protective Device Coordination

We analyze relays, breakers, and fuses to make sure the right device clears the fault quickly and safely without shutting down your entire system.

5. Equipment Rating Evaluation

We check that your electrical equipment such as breakers, panels, switchgear, and transformers are rated to handle the fault currents in your system. If anything is undersized or at risk, we’ll point it out so you can address it before it becomes a problem.

6. Arc Flash Calculations

Using NFPA and IEEE methods, we calculate incident energy levels, approach boundaries, and PPE categories. This tells you exactly what protection your workers need.

7. Report & Action Plan

We deliver a stamped engineering report with one-line diagrams, hazard levels, and recommendations. We’ll meet with you to go over the results and talk through mitigation options.

8. Labeling & Training

Finally, we provide NFPA-compliant arc flash warning labels and, if you’d like, on-site safety training so your team knows how to work safely.
