Verified 2026-10-24 Confidence: High

Clause 5.4.3.4 of IEEE 1547.1-2020 passes the undervoltage trip type test when the equipment under test stops energizing and trips inside the clearing time that IEEE 1547-2018 sets for each range, and when its evaluated adjustment ranges for magnitude and for duration cover the allowable ranges of that standard.
