Ayman El-Hag

Ayman El-Hag received his PhD degree from the University of Waterloo in 2003. He joined the Saudi Transformer Co. as a quality control and testing engineer from 1993 to 1999. His main duties included implementation of ISO 9001 provisions and the testing of distribution transformers as per IEC 60076.

Currently, Dr. El-Hag is an Associate Professor, Teaching Stream in the Department of Electrical and Computer Engineering at the University of Waterloo. His main area of interest is condition monitoring and diagnostics of electrical insulation. Dr. El-Hag received funding from NSERC and the Qatar foundation to conduct research related to the inspection of outdoor ceramic insulators, transformers and the design of non-ceramic insulators. The total value of the funds is more than two million Canadian dollars. He has published many referred journal and conference papers in the area of monitoring of outdoor insulators and transformers.

Dr. El-Hag is a registered engineer in Ontario, a senior member of IEEE, a guest editor for Energies special issue “High Voltage Engineering and Application”, was an associate editor for the IEEE Dielectric and Electrical Insulation Transaction (2018-2019) and the middle east editor for the IEEE Insulation magazine (2016-2018). He is also a member of the IEEE outdoor insulation committee and the IEEE Std 1523 (IEEE Guide for the Application, Maintenance, and Evaluation of Room Temperature Vulcanizing (RTV) Silicone Rubber Coatings for Outdoor Insulation Applications).
