Abstract

This work presents Ferranti effect simulation of an unloaded long transmission line using transmission line hardware simulator. From the conducted experiment with transmission line simulator, the values of three phase voltages at sending end and receiving end were found, which proves the Ferranti effect. Further in this work, the influence of the Ferranti effect on the voltage at the receiving end when changing the line length is shown and how to overcome this effect by compensating an inductive reactor and a switching transformer taking into account a 400 km transmission line. It is concluded that shunt inductive reactance compensation will be helpful to reduce the Ferranti effect in long transmission line and maintain the acceptable voltage at the receiving end. Tap changing transformer will be useful in medium transmission line to maintain the voltage at the receiving end. This will reduce the voltage stress on the insulators in transmission system.
