THD Overload: How Harmonics Destroy Power EquipmentWhen Actual Grid THD Exceeds Limits (e.g., Voltage THDv > 5%, Current THDi > 10%), It Causes Organic Damage to Equipment Across the Entire Power Chain — Transmission → Distribution → Generation → Control → Consumption. The Core Mechanisms Are Additional Losses, Resonant Overcurrent, Torque Fluctuations, and Sampling Distortion. Damage Mechanisms and Manifestations Vary Significantly by Equipment Type, as Detailed Below:1. Transmission Equipment: Overheating, Aging, and Drastically ReducedEcho11/01/2025 -
Harmonic THD Impact: From Grid to EquipmentThe impact of harmonic THD errors on power systems must be analyzed from two aspects: "actual grid THD exceeding limits (excessive harmonic content)" and "THD measurement errors (inaccurate monitoring)" — the former directly damages system equipment and stability, while the latter leads to improper mitigation due to "false or missed alarms." When combined, these two factors amplify system risks. The impacts span the entire power chain — generation → transmission → distribution → consumption — afEdwiin11/01/2025 -
