The high-frequency performance of vertical earth rods is important for designing earthing systems and lightning protection systems. In this work, experimental investigations on the high-frequency and impulse response of vertical earth rods with horizontal electrode enhancements are described. The rod electrode systems are installed at the Cardiff University outdoor earthing test facility and variable...

Analytical and numerical simulation techniques have been developed for the calculation of earth resistance/impedance and to estimate the potential distribution in the vicinity of earth electrodes. However, very little literature is available on experimental validation of these calculation techniques. To address this, a programme of experimental tests on various earth electrodes has been carried out...
In this paper, a numerical model is developed to determine the earth impedance of transmission towers, which can incorporate the effect of the variations of the tower resistances along the line, the end effect of the terminating substation and the effect of the auxiliary current electrode. The model is based on the computation of the potential at the test tower and the potential at any point on the...
