The IEEE 1584 empirically derived model was chosen for arc flash analysis due to the model's capability to accurately account for a wide variety of setup parameters including:

• Voltages in the range of 208 V to 15 000 V, three-phase (line-to-line).
• Frequencies of 50 Hz or 60 Hz.
• Bolted fault current (rms symmetrical):
• 208 V - 600 V : 500 A to 106 000 A
• 601 V - 15 000 V : 200 A to 65 000 A
• Gaps between conductors:
  • 208 V - 600 V : 6.35 mm (0.25 in) to 76.2 mm (3 in.)
  • 601 V - 15 000 V : 19.05 mm (0.75 in) to 254 mm (10 in.)
• Working distances of 305 mm (12 in) or larger
• Fault clearing time: no limit
• Enclosure dimension limits:
  • Maximum Height or Width: 1244.6 mm (49 in.)
  • Maximum Opening Area: 1.549 m2 (2401 in2)
  • Minimum Width: The width of the enclosure should be larger than four times the gap between conductors (electrodes).
• Electrode Configurations:
  • VCB: Vertical conductors/electrodes inside a metal box/enclosure
  • VCBB: vertical conductors/electrodes terminated in an insulating barrier inside a metal box/enclosure
  • HCB: horizontal conductors/electrodes inside a metal box/enclosure
  • VOA: vertical conductors/electrodes in open air
  • HOA: horizontal conductors/electrodes in open air 

There are alternative calculation methods for system parameters which fall outside the range of the model. For cases with vertical electrodes in open air (VOA electrode configuration) where voltage is over 15 kV or gap between conductors is more than 254 mm. (10 inches), the theoretically derived Lee method can be applied and it is implemented in Arc Flash Analytic version 6.0. The Lee method based upon Lee’s paper, is applicable for three-phase systems in open air substations, and open air transmission and distribution systems. This model is intended for applications where faults will escalate to three-phase faults. Where this is not possible or likely, this model will give a conservative result.
