The worksheets are derived from equations published in IEEE 1584-2002tm. Using the results of the calculations from these equations does not insure that a worker will not face injury or death from an arc flash. Following NFPA 70E and IEEE 1584 procedures and wearing the proper protective equipment will

A similar situation occurred when the original 2002 edition of IEEE 1584 was first released. People found themselves trying to sort out the details of how to use the new concepts. Some of the initial uncertainty and confusion were questions such as: Do you measure the actual bus gaps or use the defaults from IEEE 1584 that were also included in ...

It has been sixteen long years since IEEE 1584 – IEEE Guide for Performing Arc-Flash Hazard Calculations was first published in 2002. This standard was highly celebrated back then because for the first time there was an internationally recognized standard that provided a method to calculate the arcing short circuit current, incident energy ...

NFPA 70E stops short or requiring a specific calculation method for the incident energy analysis. However, globally most use the IEEE 1584 standard. Incident Energy is defined by both NFPA 70E and IEEE 1584 as: The amount of thermal energy impressed on a surface, a certain distance from the source generated during an electric arc event.

125 kVA – Going, going, gone! After much speculation about the fate of the 125 kVA transformer “exception”, the 2018 Edition of IEEE 1584 – IEEE Guide for Performing Arc-Flash Hazard Calculations has finally been published and made it official.

The first edition of IEEE 1584.1 was published in 2013 as a document to assist in specifying arc flash studies based on the original 2002 Edition of IEEE 1584. This latest edition has been updated to reflect the 2018 Edition of IEEE 1584. Scope

When the first edition of IEEE 1584 was published in 2002, it accounted for the effect of the enclosure by considering one of three different sizes. Depending on whether the equipment was classified as medium voltage, low voltage switchgear/power or low voltage distribution such as panels and motor control centers, the incident energy and arc ...
