    Jim Phillips takes you on a deep dive with the 2018 Edition of IEEE 1584 - Guide for Performing Arc-Flash Studies. In this 16-hour online training class, he takes you behind the scenes and answers “why” when it comes to this standard..

    Highlights of the Major Changes 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 are performed at 1 of 3 voltage levels with interpolation to actual voltage
  • The 125 kVA transformer exception was replaced.

  • Using his ever popular calculation worksheets, Jim takes you through many example problems to illustrate using the equations, k constants and the effect of parameters such as enclosure size, electrode configuration, voltage and more. 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.

    What is an Arc Flash Study?

    2018 IEEE 1584 Major Changes

    As part of an arc flash study (Risk Assessment) the incident energy exposure level is determined based on the working distance of the employee’s face and chest areas from a prospective arc source. Arc-rated clothing and other PPE is selected with a rating sufficient for the incident energy exposure and shall be used by the employee based on the specific task. IEEE Std. 1584 tm, IEEE Guide for Performing Arc Flash Hazard Calculations is the method used globally for calculating the prospective incident energy.
    NFPA 70E and CSA Z462 also require determining the arc flash boundary, which is the distance from a potential arc source where the incident energy is 1.2 cal/cm2. This value is considered to be the point at which the onset of a second-degree burn occurs. Live work performed outside of the arc flash boundary does not require PPE, although the risk of some injury still exists.

    The concept of these requirements is simple. At each location, the arc flash study is used to determine: The perspective incident energy exposure for a worker’s chest and face, the rating of PPE based on the perspective incident energy, the arc flash boundary.

    Although NFPA 70E provides more generalized PPE tables as a simplified alternative for PPE selection, an arc flash calculation study requires performing calculations to estimate the magnitude of incident energy exposure. These calculations are based on specific details, including the available short circuit current, device clearing time, grounding, arc gap distance, equipment type, and many other factors.

    This information, as well as data regarding electric shock protection and approach limits, can be included on the arc flash warning labels placed on the equipment under study. Before conducting energized work, a qualified worker can refer to the label and obtain the data necessary for the shock hazard risk assessment and the arc flash hazard risk assessment as required by NFPA 70E and CSA Z462.

    Although an arc flash study can appear to be complex, it can be more manageable when broken down into basic steps as outlined in this online training program.
