Abstract :
In this paper, experimental and analytical studies of the electromagnetic transient response of a buried bare wire and a ground grid are presented. The electromagnetic transient response of a ground grid has effects on induced surges in low-voltage and control circuits of power stations, substations, and telecommunication stations. Therefore, the experimental and theoretical examinations for the electromagnetic transients response of a buried bare wire and a ground grid have been carried out. However, these examinations need verifications with field tests in practical use. To solve these problems, the measurements of the electromagnetic transient response of the buried bare wire and ground grid are carried out under various experimental conditions. The experimental results are compared with results calculated using Sunde´s theoretical formulas, and the validity of the theoretical formulas is examined. Moreover, a calculation model based on both the theoretical formulas and electromagnetic transients program is proposed. From these examinations, it is clearly shown that the results calculated using the theoretical formulas can reproduce the experimental results.
