Arc flash is the term describing an extremely dangerous electrical hazard when uncontrolled current passes between two conductors. When voltage is high enough (over 480V), the intense heat of the arc ...

Electrical crews rarely operate in ideal conditions. Most of the time, crews are making repairs and improvements in vast, open spaces. That makes workers more vulnerable to risks and hazardous ...

An electrical arc flash can occur when someone is verifying the presence of voltage, checking the balance of current, operating a switch, inspecting an energized cable or bus connections during ...

Reducing personal injuries from arc flash events should be the main goal of any arc flash hazard assessment. Many facilities have locations where the arc flash energy levels are extremely high. These ...

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.
