Arc flash explosion
Pressure waves generated by an arc flash explosion can carry a force up to thousands of pounds per square inch, which is powerful enough to knock down or throw nearby workers, and cause damage to the eardrums, lungs, brain and other organs. Other effects of arc blast include: Searingly high temperatures.
What happens during an arc blast?
The arcing results in a tremendous amount of energy being released as current flowing through ionized air. An Arc Blast, separate from an Arc Flash, is a supersonic shockwave produced when the uncontrolled arc vaporizes the metal conductors.
What's the difference between arc flash and arc blast?
“Arc flash” is the extremely high-temperature discharge produced by an electrical fault in air. “Arc blast” is a high-pressure sound wave caused by a sudden arc fault.
