Abstract

This project focused on the modelling and analysis of Metal Oxide Varistor Surge Arrester Model Type in Transmission Line for Overhead Protection. The primary cause of damage to electrical system equipment is transient overvoltage occurring in the power system. Therefore, the metal oxide surge arrester serves as a protective device to mitigate the impact of lightning and safeguard high and medium voltage system devices from switching overvoltage and lightning. The project utilized the metal oxide surge arrester to protect the transmission line insulations and equipment connected to the transmission tower. The simulation involved a lightning strike on the transmission tower, inducing a sudden high voltage in the system that could potentially damage other equipment. Moreover, this project simulated the dynamic properties of metal oxide varistor surge arresters using various proposed models, including the IEEE model, Pinceti model, and Fernandez model. These models were implemented in the PSCAD simulation software. A 1.5km single line of 275kV with 5 towers was modelled and simulated using the PSCAD software to conduct performance tests on different types of metal oxide varistor surge arrester models proposed for protecting the towers and transmission lines.
