S&C’s Power Systems Services Presents:

Application and Performance of Electrical Distribution Equipment Seminar

This seminar has been specifically designed for technicians, technologists, or graduate tngineers working at different responsibility levels in electric utility departments, consulting engineering firms and equipment manufacturers who are engaged in material specification, system planning, design, project management, or operation and maintenance.

The unique seminar offers a blend of theoretical and practical information gained by the speaker during his long career in industrial plants and hydro utilities. The objective of the course is to outline the characteristics of the electrical equipment used in the construction of power distribution system, with special emphasis on the application and subsequent performance. Design requirements and ratings, which must be considered at the time of component selection, will also be discussed. A number of “what went wrong” examples will be discussed.

Throughout the course, reference will be made to applicable Canadian and American Standards, e.g. CSA, ANSI, CEA, etc. The operation of some components will be explained using actual samples. You will derive the most benefit when you solve the practical assignments.

Instructor

Wallas H. Khella, Ph.D., P.Eng.

Wallas has spent 13 years in industrial plants, followed by 25 years with Ontario electrical utilities. He has a thorough knowledge of overhead and underground distribution systems, distribution substations and protective devices.

Over the last 30+ years, Wallas has taught various courses in Power System Engineering as part of the Continuing Educational Program of The University of Toronto for the IEEE and to several professional development organizations in Canada and abroad. In recognition of his contributions to professional education, the IEEE Toronto Section has named a scholarship in his honour. Wallas is a fellow of the Engineering Institute of Canada and a Senior Life Member of IEEE.
