The proper modelling of transmission line towers
and conductors plays an essential part in the travelling-wave analysis of fast front overvoltages due to lightning surges in overhead power lines connected to Gas Insulated Substations.
This paper investigates the effect of different simulation
component models on the transient overvoltages produced at the entrance of the Gas Insulted Substation. A new combined tower model that takes into consideration both the bracings and the damping effect of each tower section is proposed.
