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 ...

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 arc flash is a sudden discharge of energy, connecting a component with the ground or another voltage phase in the same system through the air. This discharge can result from loose connections, ...
