One of the parameters to be considered when designing the grounding system is the soil resistivity. The soil resistivity is expectedly to change over time due to changes in water content, soil migration, chemical and fluid composition and temperature in soil. Due to all of these changes, it may affect the relative ground resistance at steady state, RDC and ground potential rise (GPR) values. While many studies have reported that under high impulse currents, ionisation process in soil would occur, with the changes in soil resistivity over time of ten months, responses of ground electrodes under high impulse currents over time would be expectedly to be relatively different. In this work, test results on the soil resistivity, RDC values and responses of ground electrode under high impulse currents over time are presented and discussed.
