Power Quality Monitoring, Harmonic Analysis

This course provides a practical understanding of power quality monitoring and harmonic analysis in electrical power systems. It explains common power quality problems such as voltage fluctuations, sags, swells, interruptions, transients, and waveform distortion. Participants learn the fundamentals of harmonics and their impact on electrical equipment and system performance. The course covers harmonic sources generated by non-linear loads such as variable frequency drives, UPS systems, rectifiers, and power electronic devices. It introduces power quality measurement techniques and the use of power quality analyzers for monitoring electrical parameters. Participants learn how to assess voltage, current, frequency, power factor, THD, and harmonic distortion. The course also explains harmonic spectrum analysis and interpretation of measurement results. Practical approaches for identifying the causes of power quality issues and evaluating their effects are discussed. Mitigation techniques such as passive and active harmonic filters, power factor correction, and proper system design are covered. The course helps engineers and technicians improve system reliability, equipment performance, energy efficiency, and compliance with applicable power quality standards.
