Abstract
Absract. The main role of 500 kV extra high voltage Gas Insulated Substation in transmission system is serves connection between the electrical generation and transmission system. To improve equipment performance and the quality and reliability of electricity distribution need time to maintain gas insulated line compartment but preparation to maintenance requires a long time, limited maintenance duration, long implementation of gas evacuation. This paper is object to redesign Gas Insulated Switchgear to semi Air Insulated Switchgear on 500 kV side and 150 kV side with new design of Gas Insulated Line compartment in order to accelerate maintenance, gas evacuation job. After redesign GIS to Semi AIS show maintenance IBT after redesign is 25 hours faster and duration anomaly on GIL after redesign 24 hours faster.
