Unlocking the Hidden Impacts of Harmonics on Power Quality and Grid Reliability
This white paper explores the origins, effects, and mitigation of harmonic distortion in electrical power systems. It details how modern nonlinear loads introduce harmonics, leading to excessive heating, equipment failures, and reduced efficiency. The paper emphasizes the interconnectedness of customer current distortion and utility voltage quality, reviews measurement and mitigation strategies, and highlights the importance of industry standards and collaboration for effective power quality management.
Key topics include:
- What is Harmonic Distortion?
- Steady-State vs. Transient Distortion
- Relationship Between Voltage (Utility) and Current (Customer) Distortion
- Problems Caused by Harmonics
- Harmonics Mitigation
- Measuring Harmonics
- Harmonic Standards
Why utilities should care:
Harmonic distortion drives up operational costs, shortens asset lifespans, and complicates grid management. Understanding and addressing harmonics is essential to maintain reliability, reduce losses, and comply with power quality standards, ensuring efficient service delivery.
