Understanding Lightning Protection

Lightning can have a devastating effect on power supply assets, damaging buildings, power structures, communications and other essential equipment – yet this damage can be easily, and cost-effectively, avoided.

EA Technology is a world leader in lightning risk assessment, protection and earthing systems, and this course is designed to share that knowledge and expertise, to help you avoid the costly and potentially catastrophic consequences of a lightning strike.

The course covers everything from the basics of lightning and its effects, to the use of risk assessment in the formulation of protection strategies. It will not only provide you with a clear understanding of the threat from lightning and the protection options available, but also introduce you to the economics involved in protection system selection.

EA Technology are a leading authority on lightning protection and have developed and operate one of the principal lightning location systems on the market.  This course is delivered by expert practitioners in a highly specialised field, and as a result of attending you will gain:

  • An understanding of how lightning occurs and behaves
  • An insight into lightning risk and applying risk assessment
  • Knowledge of the effects of lightning on buildings and structures
  • A detailed guide to the application of the BS6651 and EN62305-2 standards
  • See how software tools can be used to map lightning strike offline and in real-time and how to perform analysis on historic data
  • An understanding of the effects and issues associated with telecommunications infra-structure
  • Increased understanding from examining individual case studies
  • An update on new developments and future technologies
