Shielding failure occurs when lightning strikes directly at a phase conductor bypassing the overhead shielding wires. Since higher magnitude of lightning currents are more likely to terminate on the grounded shield wires, shielding failures are typically from low magnitude lightning currents. Back-flashovers, on the other hand, occur when lightning strikes the shielding shield wires or the tower structure and the resulting voltage developing on the tower from its impedance causes a flashover across the line insulation. Surges from back-flashovers are significantly higher in magnitude than those from shielding failures and have very steep fronts, therefore it is more dangerous to the substation equipment. For this reason, in this project, only surges from back-flashovers are considered. Often, lightning related flashover risks from shielding failures and back-flashovers are indicated by Shielding Failure Flashover Rate (SFFOR) and Back-Flashover Rate (BFR), respectively. This project requires research and evaluation of the ideal location of the surge arrester and the number of surge arrester that is needed to be install inside the 132kV substation in order to overcome the lightning overvoltage and optimize the substation performance. In addition, identify the magnitude of overvoltage that may be imposed on the substation equipment’s from lightning surges and assess the adequacy of the insulation withstand capability of the installed equipment to the lightning overvoltage. 2023-05-03T16:41:01Z 2023-05-03T16:41:01Z 2020-02 https://irepository.uniten.edu.my/handle/123456789/21360 en application/pdf
