What Causes an Arc Flash? Arc flash is caused by several different factors, but chief among them is a spike of electricity, called a voltage transient, switching from reactive loads or lightning strikes. The flash can be incredibly brief — shorter than a few microseconds. Other causes of an arc flash can include: Human error: touching a test ...
What is arc flash? An arc flash is a release of electrical energy that causes an explosion which can reach temperatures of up to 20,000 degrees Celsius. An arc flash usually occurs in large switchboards but can also occur in smaller switchboards, electricity supply pillars or large electrical equipment. Common causes of arc flash include:
· Arc flash refers to the light and heat produced by the event, while arc blast is responsible for change in air pressure and sound pressure (the “sonic shockwave”). Often, the arc blast will throw people from the flash as the explosion causes air to rapidly expand.
