An arc flash is defined as a hazardous explosion of energy from an electrical circuit, or a type of discharge that results from a low-impedance connection through air to ground or to another voltage ...

When electrical equipment must be maintained or repaired while energized, an arc flash hazard may be present. Affected workers need to know what steps should be taken to stay safe. Arc flash warning ...

Every so often, the electrical industry is able to add to our understanding of what makes a safe, well-designed electrical system. This knowledge can have a profound effect on the way we design, ...

Tri-State Generation and Transmission requires its linemen to wear flame-retardant clothing and use the proper tools and personal protective equipment when working ...

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, ...

Switchgear comprises electrical disconnect switches, fuses and/or circuit breakers that control, protect and isolate electrical equipment in electrical power systems. A switchgear fault (phase loss, ...

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.

Arc flash has always been a relevant topic — as long as electrical controls and power distribution have been around. Jerred Davis, Systems Consultant for Rittal, talks to us about Arc Flash. He ...

An arc flash is the explosive energy released when an electrical fault causes an arc. This rapid release of energy causes excessive temperatures in addition to air and metal in the path of the arc ...

Something that happens in a split second can impact a worker and his or her family for the rest of their lives. While arc flash injuries can be fatal, those that aren’t fatal still require significant ...

In a typical television transmitter installation 30 years ago — at a time when big power was coming into play (three-phase, 460VAC) — power was fed from a transformer located just outside of the ...
