An arc flash (also called a flashover) is the light and heat produced as part of an arc fault, a type of electrical explosion or discharge that results from a low-impedance connection through air to ground or another voltage phase in an electrical system.. Arc flash is distinctly different from the arc blast, which is the supersonic shockwave produced when the uncontrolled arc vaporizes the ...
Performing an arc flash study is typically done in phases or layers. The fundamental phases are data collection, followed by short circuit analysis, and then arc flash study. The goal is to collect as much information about the site as possible and reduce the amount of assumptions you make so your calculations are better.
An arc flash study, also referred to as an arc flash analysis or a hazard analysis, is an on-site study of your facility, conducted by a trained expert to evaluate your electrical system and note areas potentially presenting a risk to your personnel or equipment.

Arc Flash Risk Assessment. The arc flash risk assessment is the process that is undertaken to determine the level of hazard that exists at each electrical enclosure such as a control panel, panelboard, disconnect switch or switchgear.
Arc Flash Training. Of these four phases, only Step 2, the engineering analysis and report preparation, are done off site. A properly executed Arc Flash Study includes: Complete Study of your electrical panels; Single or One-Line Diagram of the electrical distribution panels in your system
ETAP Canada is an independent, privately held ETAP sales office, which provides sales, service, and training for ETAP power system analysis software in Canada.
Where E is the arc flash energy, E n is the normalized arc flash energy, I a is the arcing current, C f is the calculation factor, t is the duration of the arc, D is the distance from the arc to the person (from IEEE 1584, Table 3), X is the distance X-factor, k 1 and k 2 are constants, and G is the conductor air gap.
Protective device coordination study (to reduce severity and improve clearing time of faults) Arc flash hazard assessment (to calculate approach boundaries and incident energy levels) PPE and safe work practice recommendations (based on the arc flash analysis) Equipment labels (to identify the Arc Flash Hazard for workers)
Goals of Arc Flash Safety. One of the critical steps for optimizing safety is to use proper PPE (Personal Protective Equipment). The goal of arc flash mitigation is to reduce the arc flash energy and the PPE to a level that allows normal tasks to be performed on equipment.
