ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can ...

A fire at the PATH Newport Station that left 19 people injured earlier this month has been linked to signs of “electrical ...

Rising rack densities lead to increased incident energy, elevating the risk of arc flash hazards. Proactively addressing ...

When analyzing arc flash hazards in an electrical distribution system, it is not uncommon for equipment with high incident energy levels to be a great distance from the immediate upstream interrupting ...

The purpose of this paper is to examine the application of low-voltage circuit breakers to control the energy released during an arc-flash occurrence. It contrasts arc-flash incident-energy values ...

Q&A: Preventing Arc Flash and Shock Hazards A safety expert sits down with OH&S magazine to discuss why implementing proper risk assessment goes hand-in-glove with having the right PPE. By David Kopf ...

The Causes of Arc-Flash In my previous article, I explained that commonly proposed solutions for arc flash include special clothing and “fast-acting” relays whose purpose is to de-energize the circuit ...

Every day, an estimated five to 10 arc flash incidents occur and more than 2,000 people are hospitalized each year, according to The National Fire Protection Association (NFPA). With arc flash and ...

Arc-flash mitigation in battery-based energy storage systems To mitigate arc-flash hazards, arc-flash relays detect the light from an emerging arc-flash and send a trip signal to an upstream circuit ...

Within electrical equipment, the arc flash risk can vary dramatically, and this typically results in a maximum “zone” of risk associated with the line-side of the main circuit breaker.
