What Is Arc Flash Mitigation?
Arc flash mitigation starts with an onsite, non-invasive assessment to reduce the risk of electrical explosions.
When a facility faces potential arc flash hazards, Excel Engineering can help implement solutions that address the danger and improve electrical safety.
How Our Arc Flash Process Works
Our team conducts a thorough on-site evaluation to gather essential data on your electrical system—equipment specs, breaker settings, cable types, transformer ratings, and fault current sources.
Using industry-leading software, we create a digital model of your system to simulate fault conditions and calculate incident energy levels.
We perform a detailed arc flash study in accordance with NFPA 70E and IEEE 1584. High-risk areas are identified and ranked for mitigation based on calculated incident energy and equipment criticality.
We then engineer targeted solutions to reduce arc flash energy, such as:
- Reconfiguring protective device settings
- Specifying arc-resistant gear or fast-acting relays
- Specifying remote operation or racking systems
- Design and sizing of current-limiting devices
We analyze device coordination to ensure fault isolation happens quickly and selectively, minimizing the risk of cascading failures.
We install NFPA 70E-compliant arc flash labels and provide full documentation, including:
- One-line diagrams
- PPE requirements and safety recommendations
Finally, we train your personnel on proper PPE use, label interpretation, and safe work practices. Ongoing consulting is available to maintain safety and compliance as your system evolves.
We're ready to help with your next project.
