Distribution protection equipment have become so sophisticated and advanced in recent years that they can accommodate numerous protection functions and capabilities that once were only in the realm of transmission networks. As such, protective equipment in distribution networks can now match the functionality of the same devices in transmission. Similarly, test equipment designed for verification of protection systems have become very practicable in application to both transmission and distribution networks’ equipment and assets. There is now a need to apply design principles in distribution networks that are aligned to transmission concepts. This paper aims to put forward a case for earth grid design in distribution networks by showcasing a study in which transmission design and testing principles were applied to a distribution site, and discuss the results obtained from this approach.
