Abstract :
In this paper, the overvoltage on a transformer terminated at a transmission line through a cable is considered. Also, the effects of the length and size of the cable on the amplitude of overvoltage and its harmonics are investigated. Simulations are performed using EMTP and their results show the longer cable the less amplitude of overvoltage on the terminal of the transformer.
