Abstract
1584 has been the premier standard for arc-flash hazard arcing current, incident energy, and arc-flash boundary calculations since it was first published in 2002. After extensive testing, and a long model development and validation period, the long-awaited revision of Std. 1584 has been published. The purpose of this paper is to introduce 1584-2018 IEEE Guide for Performing Arc-Flash Hazard Calculations to the industry. The model range and the rationale for selection of the parameters is discussed for quantities such as voltage, bolted RMS short-circuit current, gap between conductors, enclosure dimensions, fault duration, working distance, and system frequency. Rationale is provided for the selection of electrode configurations and various enclosure (box) sizes and arrangements. This model is based on over six times the tests performed for the model used in the 2002 standard. It provides additional modeling of electrode configurations which were not included in the 2002 version. Some guidance on identifying electrode configurations are provided.
