Lightning Protection, Risk Assessment and Design: BS EN 62305


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.
