<p>Methods and apparatuses for measuring an electrical property of the ground. The apperatus includes a graphite electrode (10). The graphite electrode includes a graphite body (12) and a first (14) and second (15) opening. The first opening extends longitudinally throughout the graphite body and is configured to receive a multi-wire cable (18). Using a graphite electrode, measurements of the ground resistance can be made over a long period of time.</p> |
