Arc Flash Analytic

Description

Arc Flash Analytic version 6.0 (AFA v6.0) software program has been developed based on IEEE 1584 2nd Edition year 2018 Guide for Performing Arc-Flash Hazard Calculations as an easy to use and comprehensive tool for calculating arc incident energy and arc flash boundary, for determining limited, restricted, prohibited approach boundaries and hazard risk category required by NEC / CEC and OSHA when work is to be performed on or near the energized equipment. Also, the program allows one to calculate initial pressure generated by arc blast and arc flash TNT (TriNitroToluen) equivalent.

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.
