Abstract
Methods and apparatuses for measuring an electrical property of the ground. The apparatus includes a graphite electrode. The graphite electrode includes a graphite body and a first and second opening. The first opening extends longitudinally throughout the graphite body and is configured to receive a multi-wire cable. The second opening is configured to secure one or more wires of the multi-wire cable to the graphite body. Using a graphite electrode, measurements of the ground can be made over a long period of time without having to clean or otherwise maintain the electrodes because the graphite material withstands operating conditions over many years without degradation.
