Verified 2026-10-27 Confidence: High

IEEE 1159-2019 warns that many measuring instruments compute imbalance by the ANSI C84.1 method, the maximum deviation of a phase-to-phase voltage from the average divided by the average, which agrees with the sequence ratio only when harmonic content is low and zero sequence is small.
