Verified 2026-10-27 Confidence: High

In IEEE 1159-2019 notching is a periodic voltage disturbance caused by the normal operation of power electronic converters as current commutates from one phase to another, creating a momentary short circuit between two phases; it is steady state yet carries high-frequency content, so it sits between transients and harmonic distortion and may exceed what typical harmonic instruments can characterize.
