IEEE 1584-2018 - Guide for Performing Arc-Flash Hazard Calculations

Overview

IEEE 1584-2018 is the IEEE guide that describes how to perform arc-flash hazard calculations, and the publisher's page identifies the 2018 arc-flash model together with its errata and supplementary calculators. It is IEEE copyright and paid, and this record rests only on the publisher's public page and metadata; the full text has not been read and is not distributed. The document is a basic method reference used for the quantitative assessment of arc-flash hazard in electrical installations.

In this library the document serves as the method reference for the local incident-energy screen for three-phase systems from 208 to 600 V. The calculation considers full and reduced arcing-current cases, and for these to be applicable, evidence of the total clearing time is required. The result thus depends not only on fault current but on how fast the protective device actually clears; if that time cannot be evidenced, the calculation is unsupported.

An important caution in the record concerns how results may be used: they are preliminary study values and are never posting labels. The local implementation is also independently unapproved, while the publisher page describes the 2018 model, its errata and supplementary calculators. This content is therefore no substitute for an engineering review and independent verification. The document's limit here is that this record rests on metadata only; for details such as equations, coefficients and electrode configurations, the standard itself should be consulted. The standard's DOI is 10.1109/IEEESTD.2018.8563139.

Key points

1. IEEE 1584-2018 is a guide for performing arc-flash hazard calculations (IEEE, 2018).
2. In the library it is the method reference for the local 208-600 V three-phase incident-energy screen.
3. Full and reduced arcing-current cases require applicable total-clearing-time evidence.
4. Results are preliminary study values and never posting labels.
5. The publisher page identifies the 2018 arc-flash model, its errata and supplementary calculators.
6. The local implementation is independently unapproved.

Using it in design

• Present the arc-flash screen as a preliminary study tool for 208-600 V three-phase systems and label results as study values, not posting labels.
• Require evidence of the protective device's total clearing time for the full and reduced arcing-current cases.
• In the interface, state that the result comes from an independently unapproved local implementation and needs engineering review.
• Link to the publisher's resources for errata and supplementary calculators.

Who should read it

Electrical engineers carrying out arc-flash preliminary studies for installations, or building a tool that does so.
