| Title: Lightning Challenges in Ontario |
| Speaker: William Alexander Chisholm E-mail: W.A.Chisholm@ieee.org Telephone: (416) 207-6982 |
| Abstract: When it comes to lightning protection of assets and infrastructure, Ontario is a province of contrasts. The number of storms and the resulting ground flash density varies widely, depending on location and time. The soil and rock in the east and north of the Province have large variations in electrical parameters, so much so that identical structures as close together as 300 m can have 100:1 differences in footing resistance. This informal one-hour talk will give some background about the lightning in Ontario and cover aspects of lightning warning, personal and group protection and relevant protection standards. Then, the audience will select some specific lightning protection case studies from a list that will include: · transient grounding in Ontario's two-layer soils · protecting a TV tower in cottage country or a sailboat in fresh water · protecting an electric power system - choice of overhead / underground, high or low voltage · protecting a large windmill · protecting an outdoor facility with a chimney and nearby instrumentation or control systems |
| Biography: Dr. William A. Chisholm is an internationally acknowledged expert in lightning protection, insulation and thermal rating of power systems. He has a BASc in Engineering Science and an M.Eng from the University of Toronto and received a PhD in electrical engineering from the University of Waterloo in 1983. Bill is a Senior Research Project Manager in the Transmission and Distribution Services group at Kinectrics, the former Research Division of Ontario Hydro. He has completed contract and project work, including forensic investigations, for more than thirty different electrical utilities, manufacturers and research organizations. Bill has prepared articles for publications as diverse as Cottage Life, Ontario Milk Producer, National Weather Digest, Journal of Geophysical Research and Insulator News and Market Report (INMR). Within the electrical industry, he was recognized with a "Best Standard" award in 1999 for the 'Guide to Improving the Lightning Performance of Overhead Transmission Lines' IEEE Standard 1243. He is also chairman of the IEEE Power Engineering Society Lightning and Insulator Subcommittee and a member of the PES Editorial Board. |
