Description
Summary:This paper discussed the transient Grounding Resistance(TGR) of a kind of simple earthing electrode. In order to study the influence of TGR, a kind of TGR testing system is adopted, which is testing the TGR under impulse current. In this paper, the round steel are utilized as the material of the earthing electrode. In addition, the TGR is calculated using FDTD method. The waveform and results of calculated with FDTD is similar to the measured results. Therefore, the accurry of the experimental system is proved. The experimental results have practical value in the project.
