Dear Compliance Colleague, You are invited to the meeting of IEEE Central New England Section EMC Chapter on Tuesday November 12, 1996 6:30p.m. featuring presentation and follow up discussion. Meeting will feature the presentation Protection of Facilities and Equipment Against Lightning and Other Transient Sources by Norman Violette, Director of the IEEE EMC Society. You will learn more how to reduce the EMC guesswork in the design stage by learning from the expert.
Surge protection of equipment is vital in today's increasingly electronic world. Transient overvoltages and surges cause equipment malfunction and damage, and result in costly down-time and repair costs. Dr. J.L. Norman Violette will provide an overview of the transient generation phenomena, discuss the mechanisms by which transients couple into and affect equipment, and discuss protection techniques and design strategies to minimize transient energy-induced failures. Specific attention will be paid to the correct installation, characterization, and selection of protective devices. Pros and cons of various techniques will be discussed and recommendations for improving transient immunity provided during the talk. Presentation will address concepts of lightning and other sources of transient phenomena. Time domain and frequency domain characteristics will be presented, followed by the coupling and interaction of transients with facilities and equipment including direct and indirect coupling modes. Protection concepts will be described followed by the description of techniques and typical protection components, with description of the characteristics of these components, including MOVs, gas tubes, transzorbs, diodes, and hybrid devices. The coordination of insulation and protection devices for high voltage transients and standards for EMC transient immunity will be reviewed. The emergence of harmonized technical standards in the European Union has produced test specifications for equipment evaluation. Dr. Violette will provide vital information on the surge testing requirements on EMC immunity standards. Dr. Violette has performed numerous transient analysis and design tasks, including the lightning protection of the Statue of Liberty, surge suppression specifications for computer and network communications equipment, and failure analysis and prevention for telecommunications equipment and facilities. Mr. Norman Violette, Ph.D, PE is President of the Violette Engineering Corporation located in Falls Church, Virginia, USA. He is the CEO and co-founder of the Washington Laboratories, Ltd. In Gaithersburg, Maryland. He is a member of the Board of Directors of the IEEE EMC Society, and Past Chairman of the Washington, DC/Northern Virginia Chapter. He has presented approximately 200 seminars and workshops in various EMI/EMC Topics in the USA, Canada, Europe, Israel, South Africa, Panama, Hong Kong, Singapore and Malaysia. He was a co-author of the "Electromagnetic Compatibility Handbook" published by Van Nostrand in 1987. Dr. Violette is on the Board of Directors of the Lightning Protection Institute. He has written a number of papers on EMC. The meeting will take place in the cafeteria of the Chomerics Facility, 77 Dragon Court, Woburn, Massachusetts on October 22, 1996 at 6:30 p.m. >From Route 128 take exit # 36, Woburn, Washington Street. Proceed North after the traffic light (Bradlees on the right), past the U.S. Post Office on the left. Dragon Court is on the left, just before the gas station. Proceed about 1 mile to the Parker Chomerics facility which is on the left. The cafeteria is located on the ground floor of the building across from building 78. A no-host dinner with the speaker will follow the meeting. In addition to this extremely valuable presentation, food and refreshments will be on Chomerics. Join us on October 17, 6:30 p.m., you can't lose.
