Lightning Protection, Risk Assessment and Design: BS EN 62305

  • 15 available

Course summary

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.

  • An understanding of the effects and issues associated with telecommunications infrastructure
  • Increased understanding from examining individual case studies
  • An update on new developments and future technologies

Good introduction to Lightning Protection and BSEN 62305. Very knowledgeable instructors, well-paced and all questions clearly answered and explained.

Ian, 29 & 30 November 2023

Excellent, would now feel confident to do risk assessments and design LPS for relatively small-scale installations I work on.

Nick, 29 & 30 November 2023

Course leader was very knowledgeable and engaging. As well as the presented content it was great to be able to get outside and undertake practical measurements.

Martin, 29-30 November 2022

A good course which would be recommended to others gaining an understanding of lightning protection. I would have liked a little more technical analysis of where systems had gone wrong, maybe supported by investigations. I will be recommending the course to other colleagues.
