The online Arc-Flash Calculator can assist in determining incident energy levels and flash protection boundaries based on circuit characteristics. This calculator prompts for two circuit parameters and uses these values to determine electrical hazard levels based on equations from industry standards and testing procedures.

The calculations and data in this calculator and procedures used for determining incident energy exposure, level of PPE, and flash protection boundary are based upon IEEE Standard 1584, Guide for Performing Arc Flash Hazard Calculations (23 September 2002).

ARC FLASH CALCULATION METHODS This course provides an overview of arc flash hazard computations suggested by IEEE ... The normalized incident energy is used to calculate the incident energy at a normal surface at a specific distance and arcing time using the formula (4). '

Arc flash application guide (calculations for circuit breakers and fuses) – photo credit: ackobieelectrical.com Arcing fault current is fault current that flows through the air, unlike “bolted” fault current, which flows through conductors, busbars, or other equipment that is (ideally) designed to withstand its effects.

Calculating the Arc Incident Energy IEEE 1584 – Guide For Arc Flash Hazard Analysis The underlying concept for safety from an electrical arc hazard is that workers can be assumed safe if the arc rating of protective clothing measured in electrical arc tests is greater than the possible arc incident energy which was established through the ...

It also provides a series of calculation methods for determining the incident energy from a dc arc flash in open air as well as in a box. The DC Arc Models paper is the basis for dc arc flash calculations that are currently used by many in the industry, including several arc flash software packages. DC Arc Flash Calculations.
