Summary:This paper presents a simplified method for calculating the tower-footing grounding impedance of a transmission line. The grounding is comprised by four counterpoises and the proposed method considers the mutual effects between electrodes. The simulations are carried out in PSPICE program and implementing naturally becomes a simple task. The electrode length and soil resistivity vary for different values. The simulation results are obtained in the frequency domain and in the time domain showing important features of the grounding response when subject to an impulsive current.
