Lightning protection in the marine environment presents special challenges. As the ground attachment path for a five-mile long spark carrying tens of kilo-amperes, the protection system has the task of safely diverting this current around crew, sensitive electronics, and hull components. However, even when the current is flowing in the water, voltage differences can cause side-flashes, both inside the boat and between the boat and the water. These present a shock hazard to the crew, produce over-voltage in electronics systems, and can blast holes through the hull. Management of the side-flash problem is the fundamental issue in the design of an effective marine lightning protection system. This podcast is your opportunity to ask questions about Lightning Protection, after viewing the presentation available on BRBR Our presenter is: Ewen M. Thomson, Ph.D., who is also CEO of Marine Lightning Protection Inc., . Author of a 1991 IEEE paper concerning the US lightning protection code that was responsible for the rewriting of that code by NFPA and ABYC, his 23 minute video "Lightning Protection of Sailboats" is now used by the US Power Squadron in their courses on boating safety. In addition to his work on boat protection, his research interests while at the University of Florida spanned the spectrum from development of fundamental electromagnetic theory to design and implementation of experimental systems for lightning research such as a multiple-station wideband electric field system at Kennedy Space Center. His teaching experience included undergraduate physics, introductory electric circuits, and electromagnetics at both undergraduate and graduate level. Since devoting full time to MLP he has concentrated on techniques and products for lightning protection of boats. This Podcast was created using
