Wind Turbines - Lightning Protection

Lightning Technologies, Inc. has developed a professional training course on Lightning Protection for Wind Turbines. The two-day course will provide design engineers, operators and maintenance personnel with the principles of lightning protection design for wind turbine blades, structures and electronic systems. It will also be useful to those concerned with specifications, codes and standards, including the recently updated draft IEC standard pertaining to lightning protection design and verification testing of wind turbines. Students will receive a course notebook containing lecture notes and related references.

The course will review the important characteristics of natural lightning including its formation, electrical and physical characteristics, and the ways in which it interacts with wind turbines. This is followed with a review of typical effects of lightning on wind turbine structures and systems. Attendees will study principles and methods for lightning protection design against direct and indirect effects for wind turbine blades and nacelles, and electrical and electronic components. The roles of current conduction, bonding and grounding will also be discussed.

Students will witness demonstrations in LTI's High Voltage Laboratory, including tests to determine protection effectiveness of blades, and high current tests of typical conductors and fittings.

J. Anderson Plumer, founder and Chief Engineer of LTI will present the course. Mr. Plumer has spent most of his engineering career in the study of lightning hazards and the development of protection methods for aerospace systems and structures. He has been involved continuously in the formulation of new verification methods and standards for aircraft and wind turbines. Mr. Plumer is the author or co-author of numerous technical publications and the book, "Lightning Protection of Aircraft".

Since 1977, engineers at LTI have been devoted to eliminating lightning hazards to advanced systems through research, development, engineering and simulated lightning testing. The company is known internationally for work in the development and certification of lightning protection for aircraft and other complex systems. Clients include most of the world's major airframe and aerospace equipment manufacturers, wind turbine manufacturers, and a wide range of others in fields such as petroleum products, utilities, telecommunications, space launch complexes, commercial electronics and recreational facilities.
