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 ...

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, ...

Masterpact Low Arc Flash circuit breakers are designed and tuned to provide balanced protection for both overcurrent and arc flash. The breakers incorporate a blow-open design that clears faults ...

Failures can occur in the electrical disconnect switches, fuses or circuit breakers that control, protect and isolate electrical equipment in electrical power systems, also known as switchgear. When a ...

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.

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 ...
