Summary:This paper studies the electric response of a common lattice tower when it is hit by a lightning stroke. Although some studies have been already done about this subject, the novelty of this one lies in the usage of a highly accurate electric model of an actual lattice tower. This model allows to calculate the impedance variation with different frequencies by using an adaptation of the well-known method of moments. Moreover, the authors also analyze how the impedance is affected when the grounding parameters and the connection to ground conditions are modified. These results are lately used to explain the electric behavior of the tower under two kinds of lightning impulses and different grounding configurations.
