Impact of Frequency-Dependent Soil on Transient Ground Potential Rise of Counterpoise Electrodes

Autor: Wagner Roberto Cirilo da Silva, Anderson Ricardo Justo de Araújo, Jose Pissolato Filho

Publikováno v: 2021 14th IEEE International Conference on Industry Applications (INDUSCON).

Tower-footing grounding impedance has a fundamental impact on the generated overvoltages in power system when a transmission tower is hit by lightning. In order to compute accurately the tower-footing grounding impedance, the frequency dependence of
