Modern mobile telecommunication systems (GSM) installations now widely use high-voltage towers for the location of their antennae. The control box and power supply for these systems are usually located at the base of the tower. Such addition to the power system has implications on the earthing system, especially under lightning fault conditions. This paper addresses the modelling of the earthing of different types of transmission towers. The impulse response of such systems is investigated to determine a) the rise of earth potential, b) the ground surface potential distribution around the tower base and c) the extent of the hot zone contours. In the transient simulation, double-exponential current impulses of standard shapes (1/5, 8/2 and 30/80) were used. Both uniform and multi-layer soils were considered in the modelling programme.
