Verified 2026-10-27 Confidence: High

IEEE 1159-2019 explains total demand distortion as the measure IEEE 519 introduced because the total harmonic distortion of a current can be misleading at light load: it expresses the harmonic current as a percent of the maximum demand current rather than of the fundamental.
