Data record `std.ieee-1547-1.definition.clearing-time`

Verified 2026-10-24 Confidence: High

Annex A.2 of IEEE 1547.1-2020 defines clearing time as the interval from the start of the abnormal condition until the DER ceases to energize the Area EPS, made up of detection time, any adjustable delay, the interposing device operating and arcing time, and the interrupting device time. The trip time, which starts at the leading zero crossing in the first half cycle where the parameter is beyond its limit, can be either a part of the clearing time or equal to it; every normative requirement is expressed as a clearing time.
