- Abstract
Regardless of the environment, the power system network must be continuously operational. Current spacer failures of Gas Insulated Busduct (GIB) have been noted as a result of a number of manufacturing and switching faults, including delamination, protrusion, depression, gap, etc. These defects have a severe negative effect on the insulator's surface, which de-energises the gas-insulated busduct device and causes a significant financial loss. For the purpose of studying the electric stress at the Triple Junction, a Functionally Graded Material (FGM) spacer is built for a three phase GIB with protrusion irregularity in this work. The stress is reduced by inserting metal inserts at the end of the zero potential. Functionally graded materials are spatially distributed with numerous filler materials to achieve homogeneous electric field stress by doping them with various permittivity values. The spacer used in the simulation is made to withstand a range of voltages as well as varied FGM gradings. Grading's impact on electric field stress is identified and further diminished with the addition of the MI to the FGM insulator. The outcomes are discussed and analysed to demonstrate how well the proposed spacer works.
