Presentation / Conference Contribution
Hasan, H., Hamzehbahmani, H., Robson, S., Griffiths, H., Clark, D., & Haddad, A. (2015, December). Characterization of horizontal earth electrodes: Variable frequency and impulse responses. Presented at 2015 50th International Universities Power Engineering Conference (UPEC), Stoke‐on‐Trent, United Kingdom

Grounding systems such as vertical and horizontal electrodes, and grids are installed in the soil to mitigate against the effects of system faults and lightning surges. Their main function is to dissipate lightning and fault currents into the earth w... Read More about Characterization of horizontal earth electrodes: Variable frequency and impulse responses.
