Earthing and lightning protection design

Routine assessments and designs, high-level policy, R&D

An effective earthing system is critical to the safety of every electrical installation. The introduction of new international standards, together with increased awareness within the electricity industry require that developers and operators of these installations carry out more thorough assessments and design studies to demonstrate safety compliance.

This is increasingly challenging against a backdrop of higher fault levels, smaller-area substations and the more prevalent use of sensitive electronic equipment both at the substation and by external third parties, where the impact of transferred earth potentials may need to be mitigated.

Lightning is the natural discharge of electrostatic electricity within Earth’s atmosphere and has the capability to be extremely destructive. Experience of lightning has shown that significant structural damage and failure / destruction of electrical systems can be caused - with the additional potential to cause injury or loss of life. However, protective measures can be introduced to existing or prospective structures to help mitigate the hazardous effects of lightning strikes.
