Department of Electrical and Computer Engineering Seminar Series

High Voltage Engineering and Insulation


Dr Wallace Vosloo


Corporate Specialist, High Voltage Engineering, Eskom Holdings SOC Ltd, South Africa

Time & Place

Mon, 26 Aug 2019 14:00:00 NZST in Link 309 Lecture Theatre


This seminar is intended to provide an understanding of the factors which dictate the behavior of overhead line and substation insulators and to generate an appreciation of the parameters which have a significant
influence on their performance and life. The emphasis of the talk is definitely on the “practical” and simple procedures, decision tables, and flow charts. Insulator types and their characteristics, electrical, mechanical, material and environmental considerations, insulator selection, tests and specifications, failure mechanisms, handling and installation practices, line and substation performance improvement, and pollution mitigation techniques are all dealt with in detail, with emphasis on practical field application.


Dr. Vosloo has over 25 years of experience in the field of High Voltage Engineering.
