Arc flash - Wikipedia
An arc flash is the light and heat produced as part of an arc fault (sometimes referred to as an electrical flashover), a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system.
What Causes Arc Flash? Electrical Arc Blast Explained | Fluke
An arc flash is an explosive release of energy from an electrical arc when the electrical current passes through ionized air. In less than a second, an arc flash is initiated from a phase to ground or a phase to phase fault.
What Is Arc Flash and How Can You Stay Safer - NFPA
May 1, 2024 — What Is Arc Flash and How Can You Stay Safer. An electric arc forms when electric current is sustained outside of its normal conductive pathway, such as in the air. Arcs can be incredibly dangerous.
What is Arc Flash? And How to Prevent It? | SafetyCulture
Oct 1, 2024 — An arc flash, also called a flashover, is a sudden electrical explosion or discharge that happens when electric current travels through the air from one conductor to another. When an arc flash occurs, the results can be extremely violent, and if a person is in close proximity to the flash, they can suffer injury or even death.
