TRAINING.

Overview

Upon the successful completion of this course, the participants will have an understanding of:

• EM Phenomena and EM Environments

Description
An understanding of electromagnetic compatibility (EMC) is essential for reliable operation of electrical/electronics equipment and systems used in commercial, automotive, aerospace and defence markets. In our multidisciplinary world, electronic circuits are designed and operated by electronic, electrical, system, mechanical and biomedical engineers. EMC aims at achieving a state when the electromagnetic environments produced by natural phenomena and other electrical and electronic devices do not cause interference in electronic equipment and systems.

This course imparts the knowledge and skills to reduce the emissions from sources that are controllable as well as to increase within reasonable cost the immunity of the equipment from getting affected.

Instructor

Ayman El-Hag, PhD, P. Eng., SM IEEE

Dr. El-Hag received his Ph.D. degree from the University of Waterloo in 2003.

He joined the Saudi Transformer Co. as a Quality Control Engineer from 1993 to 1999. His primary duties included the implementation of ISO 9001 provisions and testing distribution transformers as per IEC 60076. Since completing his Ph.D. studies, Dr. El Hag worked as a Postdoctoral fellow at the University of Waterloo and the University of Toronto from 2004-2006. Then, Dr. El-Hag moved to the American University of Sharjah, where he worked as assistant, associate and full professor from 2006 till 2018. Currently, Dr. El-Hag is a lecturer at the University of Waterloo.

Dr. El-Hag's main areas of interest are condition monitoring and diagnostics of power system assets and the application of machine learning in power engineering. He published many referred journal and conference papers in the area of outdoor insulator inspection and assessment and monitoring of transformers. Dr. El-Hag is a senior member of IEEE, an associate editor for the IEEE Transaction of Dielectric and Electrical Insulation Transaction and was the Middle East editor for the IEEE Insulation magazine from 2016-2018. Also, Dr. El-Hag is a member of the IEEE Outdoor Insulation Committee, the IEEE Std 1523 (IEEE Guide for the Application, Maintenance, and Evaluation of Room Temperature Vulcanizing (RTV) Silicone Rubber Coatings for Outdoor Insulation Applications) and the IEEE Std.2652-2021 "IEEE Guide for DC Inclined Plane Tracking and Erosion Test for Outdoor Insulation Applications."

Dr. El-Hag is a registered professional engineer in the province of Ontario.
