Analysis of switching overvoltages and protection from atmospheric overvoltages for 400kV switchgears in the Kosovo Power System using ATP/EMTP

Power systems might experience electrical problems or power outages, due to atmospheric discharges. The quality of the protection from atmospheric overvoltages will increase the life of the equipment and the reliability of the electrical system. The model for switching overvoltage calculations on the 400 kV transmission line of Kosovo Power System is analysed with ATP/EMTP software. Controlled and uncontrolled switching and controlled and uncontrolled repetitive switching of the 400 kV transmission line are analysed.
