S&C’s Power Systems Services Seminar:

Preventing Power Cable Failures: Causes, Diagnostics and Solutions

This three day technical seminar will provide an in-depth understanding of the many reasons why underground power cables fail and what steps can be taken to improve cable reliability. Prevention of cable failures and improvement of cable reliability will be the main focus of the seminar.

High reliability of underground power cables is important for every utility. Cable failures have a drastic effect on the economy as well as customer satisfaction. Improved reliability by understanding why cables fail is important for every power cable user.

This seminar has been specifically designed for managers, engineers, technical personnel and consultants involved in asset management, asset condition assessment, asset strategies, forensic investigations, testing and diagnostics of high voltage underground power cables in the electrical supply sector and in other industries.

What’s Included

The course will run from 8:30 am to 4:30 pm each day, and a bound set of notes will be provided. Refreshments and lunch will be freely available to all attendees. Contact S&C for hotel rate code after registration.

Cancellation

Cancellations must be made two weeks prior to the seminar date to allow for an 85% refund. Alternate attendee(s) are acceptable but please advise name(s) in advance of seminar.

Instructor

Harry Orton, P.Eng.

Harry Orton graduated from the University of New South Wales with a Bachelor of Engineering (Honours) in Electrical Engineering in 1966 and a Masters of Applied Science from the University of British Columbia in 1969. He graduated from the BCIT Venture Program in May, 1995.

After graduation in 1969, Harry worked at BC Hydro as an Electrical Research Engineer where he helped build one of the largest utility-based research centers in North America. For over twenty years he worked as a specialist in the field of underground power transmission and distribution cables and accessories. He progressed to the level of section supervisor in charge of Insulation Studies and then to Manager of Technical Activities. He has been a project manager on Canadian Electricity Association (CEA) and Electric Power Research Institute (EPRI) in Palo Alto, California underground cable research projects since 1977 and was Chairman of the Cable Failure Task Force from 1987 until 1993.

In 1994 he went into his own consulting engineering business as an underground power cable specialist. He is now principal and owner of Orton Consulting Engineers International Ltd. based in Vancouver and affiliated with the International Consulting Engineers. Contract work takes him to the US, Asia and to Europe.

Harry is very active in the IEEE, Insulated Conductors Committee (ICC) as Chairman of Task Group A2D on the Characteristics of Semi-conductive Shields, Co-chair of Task Group C27D on Joint Use of Power Cables and Pipe-Lines, Chairman of Task Group B15D on Cable Accessory Diagnostics, Chairman of the Transnational Subcommittee on Underground Cables and is Chairman of the International Advisory Committee of the ICPADM (The International Conference on the Properties and Applications of Dielectric Materials). He has published over 40 papers on the applications of underground transmission and distribution power cables and has given many presentations to the IEEE, ICC, research institutes, universities, manufacturers and utilities Worldwide. He has given invited presentations and seminars in Brunei, Japan, China, Singapore, Malaysia, Hong Kong, Korea, Australia, Indonesia, Thailand, Canada and the US. At present he holds six US, Canadian and International patents.

Harry is a member of CIGRE and the Scientific Committee of Jicable; both based in Paris, a member of the Vancouver Board of Trade, the Canadian Council of the Americas, the Hong Kong Canada Business Association and is a Registered Professional Engineer in the Province of British Columbia, Canada.
