COURSE OVERVIEW:

The proliferation of non-linear loads in modern industrial and commercial facilities has made harmonic distortion a critical concern for power quality and asset longevity. This course provides a comprehensive technical exploration of harmonic phenomena, focusing on the mathematical origin of non-sinusoidal waveforms. Participants will explore how power electronics, such as variable speed drives and UPS systems, inject harmonic currents into the network and the subsequent impact on system voltage.

The scope of this training addresses the rigorous measurement techniques required to quantify Total Harmonic Distortion (THD) and individual harmonic orders. It covers the technical nuances of harmonic impact on primary assets, including the overheating of transformers, the resonance of capacitor banks, and the nuisance tripping of protective devices. The curriculum provides a detailed focus on the design and implementation of mitigation strategies, ranging from passive filters to advanced active harmonic conditioners.

Coverage includes the interpretation of international standards such as IEEE 519 and IEC 61000, which define the limits for harmonic emissions and immunity. Attendees will learn to utilize power quality analyzers to conduct site audits and develop engineering solutions to restore a clean sinusoidal supply. By combining waveform analysis with practical mitigation engineering, the course equips professionals with the expertise required to manage harmonics and protect the integrity of the power infrastructure.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the mathematical basis of harmonics and Fourier analysis.
• Identify the primary sources of non-linear loads in power systems.
• Differentiate between voltage and current harmonic distortion.
• Perform professional harmonic measurements using power quality analyzers.
• Calculate Total Harmonic Distortion (THD) and TDD.
• Analyze the impact of harmonics on transformer and motor heating.
• Identify the risks of harmonic resonance in capacitor banks.
• Troubleshoot neutral conductor overheating caused by triplen harmonics.
• Design and specify passive harmonic filters (tuned and detuned).
• Evaluate the performance of Active Harmonic Filters (AHF).
• Apply IEEE 519 standards for harmonic compliance audits.
• Implement mitigation strategies for Variable Frequency Drives (VFD).

TARGET AUDIENCE:

This course is intended for Electrical Design Engineers, Power Quality Specialists, Maintenance Managers, and Facility Engineers working with sensitive electronics.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
