Verified 2026-10-27 Confidence: High

IEEE 1159-2019 cautions that a current total harmonic distortion figure can mislead, since an adjustable speed drive at light load shows a high percentage while the rms harmonic current is low, and that a complete spectrum with magnitudes and phase angles characterizes harmonic distortion more fully.
