Measures for the postprocessing of grounding electrodes transient response

Abstract

Various measures for quantifying the transient response of simple grounding systems are proposed in this paper. In addition to the standard transient impedance concept the suggested measures arising from the circuit theory are instantaneous power, average power and total energy stored in the near field of a grounding electrode. The frequency response of the grounding electrode is obtained by using the antenna model (AM) while the associated transient response is computed using the Inverse Fourier Transform. The integro-differential realtionships arising from the wire antenna theory are numerically handled via the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). A number of illustrative numerical results are presented in the paper.
