Data record `std.ieee-1584.structure.arcing-current-variation`

Verified 2026-10-24 Confidence: High

Clause 4.5 of IEEE 1584-2018 derives a reduced arcing current from the calculated arcing current by a variation factor, so that a protective device is evaluated at a lower-bound current that may fall in a slower part of its time-current curve; the arc duration is then determined again at the reduced current, and whichever pass gives the worse result is kept.

Provenance. Where this record comes from and where it is used: the cited source, the record itself and the entry that cites it.
