Power System Earthing

Our interactive two-day training course provides delegates with a practical and theoretical introduction to power systems earthing. 

The design and performance of an earthing solution can have a major impact on safety, security of electricity supplies, power quality and construction costs. Standards concerning earthing have changed, introducing new concepts, design criteria and limit values. It is essential, therefore, that companies remain fully aware of modern practice and the new design tools, measurement techniques and equipment that are available to help engineers.

Practical sessions include measurement of soil resistivity and electrode resistance using a range of equipment and the opportunity to compare different measurement instruments. Course places are limited to ensure high-quality interaction during the practical sessions, presentations and case studies. 

It is often stated that earthing is one of the most misunderstood and the least prepared for aspects of electrical power systems engineering. Earthing system design has become more complex in recent years due to higher fault currents, limited substation areas (which are often on reclaimed land), use of cables with a PVC outer sheath, the proximity of homes and third-party equipment such as telecommunication cables. The financial consequences of an accident are now accepted to be more severe with a greater readiness by claimants to pursue litigation. It is, therefore, important that companies understand the changing situation, are aware of modern practice and are able to respond in the most cost-effective manner.

Mark Davies Head of Earthing & Lightning Protection Design, RINA

Mark has over 15 years’ experience of carrying out earthing measurements, assessments, audits and earthing systems design and analysis.

His work has included projects with transmission and distribution substations, wind farms, railway supply substations and gas compressor stations. Mark has provided technical input to standard committees and is currently involved in the updating of ENA TS 41-24.

Trevor Charlton Consultant, Strategy and Solutions, RINA

Following work as a UK representative for earthing related issues on the IEC group responsible for IEC 61936-1, Trevor played a lead role in developing original earthing policy documentation for a host of UK electricity companies.

Trevor’s main area of expertise is earthing design; he has led a series of UK earthing research and development projects and has written several UK engineering instructions on earthing. He is also an experienced earthing design lecturer and presents at earthing courses in the UK, Europe, Australia and the Far & Middle East.
