New version of IEEE-1584 planned for when?

[tem1234]

Hi,

So does anybody know if a new version of IEEE 1584 is planned?

Arc-flash is relatively recent and new standard are comming, like NFPA 70E 2009 or CSA Z462 in Canada. I am just curious to know if there's somebody here who can tell if there's something planned for the IEEE 1584 and if the equation provided in this standard are subject to change soon.

Thanks

"Designation: P1584

Sponsor: IEEE Industry Applications Society/Petroleum & Chemical Industry

Title: Guide for Performing Arc-Flash Hazard Calculations

Status: Modified Revision Project

Project scope: The purpose of the guide is to enable qualified electrical engineers to analyze power systems and quantify the incident energy to which employees could be exposed during operation and maintenance work. Contractors and facility owners need this information to provide appropriate protection for employees in accordance with the requirements of NFPA 70E, Standard for Electrical Safety in the Workplace.

Abstract: This guide provides models and an analysis process for calculating the incident energy to which employees could be exposed during their work on or near electrical equipment. The models enable determination of the predicted maximum incident thermal energy and the arc-flash boundary. The process covers the collection of field data, selection of power system operating scenarios, data entry, calculation parameters, and analysis of results. Applications include enclosed electrical equipment and cables for three-phase ac voltages from 208 V to 15 kV and dc systems from 48 V to 800 V. Calculations for single-phase systems and recommendations for personnel protective equipment (PPE) to mitigate possible arc-flash hazards are not included in this guide"

In the works, not sure when.

The committee is definitely working on an update, but I have not heard anything about a schedule. This standard doesn't have a fixed update cycle. There should be a 2009 NFPA 70E, I believe. There's a pre-print out now, I think.

thanks stevenal,

interresting to see that DC system will be included but not single phase ac system

The IEEE standards are usually updated on a 4 year cycle. At 4 years, the standard can be revised, reaffirmed (left as is) or withdrawn. They often stretch this 4 years out by an additional year or 2.
