Earthing/grounding design is a safety-critical component of the HV power system. It is often one of the most misunderstood topics or specialism. In this series “Earthing Design”, we take the lid off the design process from start to finish, to demystify and bust a few of the common myths and misconceptions.

Knowing today’s electrical power system cannot be connected into a network without first demonstrating that the Earthing/grounding electrode arrangements are designed appropriately to deliver a safe system whatever the season or circumstance, software tools are increasingly doing much of the heavy lifting to deal with the complex mathematics involved and model the electrical problems in the virtual world before a single shovel breaks the ground.
