Arc Flash

Arc Flash Analysis

An arc flash is a dangerous release of energy caused by an electrical fault or short circuit. This sudden discharge generates intense heat, pressure, and light, which can cause severe injury, equipment damage, and costly downtime. Proper arc flash analysis and mitigation are essential for ensuring the safety of personnel and the reliability of electrical systems.

We’ve performed short-circuit, overcurrent protective device coordination and arc-flash studies for millions of square feet of facilities. We specialize in providing comprehensive arc flash analysis and safety solutions tailored to the unique needs of your facility. Our experienced electrical engineers combine technical expertise with state-of-the-art modeling tools to assess and make recommendations based on industry standards such as NFPA 70E and IEEE 1584.
