17/8/2020· An arc flash calculator can be used to determine incident heat energy at a particular distance and the category of PPE required. Simply enter the bolted fault current, choose a current-limiting fuse from the drop-down menu, and select "calculate." See cautionary

distance should be provided in any arc-flash hazard analysis. An arc-flash boundary is the distance from the arc source in which the incident energy is less than 1.2 cal/cm2, the energy needed to obtain a second degree burn. In the author’s opinion, fault

IE of an arc flash is dependent upon the length of the flash, the available PSC, and inversely (and exponentially) related to one's distance from the origin of the flash. NENS 09 proposes the following formulas to calculate the incident energy likely to be developed 450mm directly in …

A simplified calculator is available for specifics, and differing methods are available for determining the arc flash boundary. The main variables include the voltage, the time available for arching before the equipment’s protective equipment activates, the level of local grounding vs high resistance, how large the three phase fault is, as well as the equipment’s type and conductivity gaps.

NFPA 70E - ARC FLASH BOUNDARY The theoretical maximum arc power in MW is half the bolted 3-phase fault MVA. This happens when the arc current is 70.7% of the bolted fault current. Starting from this, the flash protection boundary is computed as (6): & »
