Lightning Protection Systems – Inspection & Testing
This EAL accredited 1 day course has been designed to provide an understanding of the lightning protection requirements of an installation in accordance with BS EN 62305.
The course starts with a description of how lightning occurs and the effects on persons, property and livestock. The theme continues with need for risk assessment for the protection from the effects of lightning. It continues with the requirements for the methods and procedures for the inspection and testing of Lightning Protection Systems.
Who should attend?
The 1 day course is aimed at those responsible for the inspection testing and maintenance of Lightning Protection Systems. The course is also suitable for engineers and technicians who have a need to know the risks to an electrical installation from the atmospheric disturbance created by lightning and how those risks maybe mitigated.
The course is modular providing both theory and practical requirements of lightning protection of an electrical installation. During the course the inspection and test requirements will be discussed and demonstrated.
