The behavior and response of power systems grounding, is determined by the variations of different parameters related with the type and magnitude of the injected current, the type of soil and the configuration of the grounding electrodes. In the specific case of power transmission lines, counterpoises are commonly used to decrease the low frequency resistance, without taking into account the characteristics that the impedance acquires once a lightning stroke reaches the grounding system. In this work the behavior of the overvoltage on the transmission tower and on the grounding system is analyzed, facing the variation of the main parameters that influence the response to slow and fast impulses.
