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.
