Systematic Approaches and Analyses on Voltage Uprating of 132 kV Transmission Lines: A Case Study in Malaysia

With the ageing infrastructure and fast-growing demand faced by utilities worldwide, voltage uprating is one of most effective solutions strategic approaches in asset management decisions. In this study, a systematic method used to propose new level, based on existing transmission lines’ physical structure, utilising appropriate techniques. Prior work conducted, 132 kV line was first examined terms clearances components attached, technical issue clearance under still air found be significant concern, particularly phase-to-earth arrangements. Next, proposed techniques processes, increasing insulation strength improving conductor clearances, were for individual tower. The tower comprehensively examines normal extreme wind conditions electrical requirements 275 lines. model then simulated using Finite Element Method (FEM)-based commercial software several lightning conditions, i.e., various basic levels (BIL) different flashover mechanisms, taking into consideration profile its analyses. study that condition able withstand BIL all thus satisfied requirement needed.
