Abstract	Earthing system is one of the main key elements in high-voltage safety management. It presents a safe working environment for workers and people passing by during a fault or malfunction of a power system. Commissioning the earth grid is a critical phase prior to the energizing of the high-voltage plant. Fall of potential method is commonly used to measure the earth grid resistance of the high-voltage infrastructure especially high-voltage transmission pole earth grid. The positions of the current and potential probe play a significant role that leads to precise results. This study endeavours to provide information in regards to the ‘Fall of Potential’ method. It includes the minimum separation required between the current probe and the tested grid. Furthermore, the novel location of the potential probe when the minimum separation between the current and electrode under test cannot be established is analysed. The case study results show the advanced accuracy in the tested result when deploying the novel method as provided in this study. The case study proves the advance accuracy of the proposed novel method especially when the testing area does not permit for a large separation between the tested grid and the current probe.
