Zusammenfassung:Lightning induced voltages in transmission lines consist of electromagnetic and electrostatic components. The electrostatic component is much less than electromagnetic one in regions where soils have a high electrical conductivity. In this paper we present mathematical models of the electrostatic component of lightning induced voltages in transmissions lines in a permafrost region where soils have a low electrical conductivity. Numerical simulations show that the values of the electrostatic component is comparable to electromagnetic one in a permafrost region.
