Abstract

The employment of series compensating capacitors in the transmission line has many benefits. One of them is that it increases the power transfer capacity especially for long transmission line. However, the drawback of the transient process is that it leads to high fault current and overvoltage during the process and it will make the system working in a very poor condition. To protect the equipment of the transmission system from the effects of lightning and switching overvoltage, surge arrester is introduced. This paper uses PSCAD software to analyse the impact when implementing Metal Oxide Arrester (MOA) or known as Metal Oxide Varistor-Arrester (MOV) in series compensated high voltage transmission line. This paper presents simulation for transmission line without the consideration of MOV and with the consideration of MOV. Result shows the suitable method to mitigate overvoltage effectively and ensure the system running stably.
