Is your Field-Working staff aware of the Arc Flash hazardous areas of the manufacturing facility?
Defining arc flash boundaries is the crucial part of the Arc Flash Analysis. Depending on the potential arc flash hazard, this boundary is calculated separately based on specific system information. There are different types of boundaries as shown in the figure below. Let’s look at what the mentioned terms mean – Boundary Arc Flash: When an arc Flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm2 (5 J/cm2 ). The flash boundary is the farthest established boundary from the energy source. If an arc flash occurred, this boundary is where …
