IT IS FINALLY HERE!  After 16 long years, the next edition of IEEE 1584 was finally published.  In this two-day arc flash training class, Jim Phillips, P.E., introduces the 2018 edition of the IEEE 1584.  Jim discusses the changes, walks you through the calculations with his new worksheets and how the 2018 edition is is used in arc flash studies.

The 2018 edition of IEEE 1584 is a major game changer.  Almost everything has changed since the original edition was introduced in 2002.

Highlights of the next edition include:

• Five different electrode configurations to enable more detailed modeling
  • Vertical electrodes in a metal box/enclosure – VCB (also in 2002 Edition)
  • Vertical electrodes terminated in an insulating barrier in a metal box/enclosure – VCCB
  • Horizontal electrodes in a metal box/enclosure – HCB
  • Vertical electrodes in open air – VOA (also in 2002 Edition)
  • Horizontal electrodes in open air – HOA
• More choices for enclosure types and sizes
• Enclosure correction factor calculation to adjust for specific enclosure size
• The effect of grounding has been eliminated
• An arcing current variation factor calculation replaces the 85% factor
• Calculations performed at 1 of 3 voltage levels with interpolation to actual voltage
• The 125 kVA transformer exception was eliminated
• Each calculation is performed in 2 steps which includes an initial calculation based on one of three voltage levels and a second calculation interpolating to the specific system voltage.    The 125 kVA “exception” was replaced.  Learn why and what has replaced it.  What about the 2 second rule?  Jim discusses all this and much more.
