AB  - This study deals with the influence of soil conductivity and a rod-to-earth electrode gap on lightning
impulse voltages. Two types of soils are considered: homogeneous and non-homogeneous/heterogeneous.
The heterogeneous soil consists of a metallic plate in contact with a parallelepiped tank filled with water or
wetted sand of different conductivities. It is shown that, for homogeneous Earth, the U<sub>50</sub> decreases when 50%
increasing the soil conductivity and the electrodes gap decreases. For heterogeneous soil configuration and
a given distance from the HV electrode to the metallic electrode, the U<sub>50</sub> is higher for lower conductivities of 50%
homogeneous soil.
