Taburan medan elektrik dan potensi dalam kawasan penebat bukan seramik di bawah kondisi kering dan bersih dikaji. Untuk memastikan bahan penebat tidak terjurus kepada tekanan elektrik yang akan menyebabkan kemerosotan,pengiraan medan elektrik perlu untuk merekabentuk peralatan kuasa tinggi. Untuk pengiraan medan elektrik ini, satu program dua dimensi iaitu program menganalisis OPERA-2D telah digunakan. Sasaran utama dalam projek ini adalah untuk mengsimulasi medan elektrik dan taburan potensi di sepanjang penebat bukan seramik di bawah kondisi kering dan bersih. Secara asasnya, empat komponen perlu dipertimbangkan dalam merekabentuk sesebuah penebat, antaranya adalah logam penyambung (elektrod), rod gentian kaca, sarung getah silikon dan pelindung cuaca getah silikon. Untuk menyelidik kesan daripada pemudahan bentuk penebat ke atas medan elektrik dan taburan potensi empat model telah direka bentuk. Antaranya adalah: (a) dua elektrod sahaja, (b) dua elektrod bersama dengan rod gentian kaca, (c) dua elektrod, rod gentian kaca bersarung getah silikon tanpa pelindung cuaca dan (d) model “penuh” penebat 34.5kV. Model yang telah dipermudahkan telah digunakan untuk menyelidik kesan penyaluran tenaga elektrik kepada sistem tiga fasa melawan sistem satu fasa ke atas medan elektrik dan taburan potensi. Kajian ke atas taburan medan elektrik untuk mengsimulasi keupayaan keamatan medan eletrik dan taburan potensi yang tinggi dalam peralatan elektrik kuasa berjaya dicapai. _________________________________________________________________________________________ The distribution of electric field and potential in the vicinity of non-ceramic insulators under dry and clean conditions are investigated. To ensure the insulating materials are not subjected to electrical stresses which can cause deterioration, the electric field calculations are required for the design of high voltage apparatus. A two-dimensional electric field analysis program OPERA-2D, has been used for calculations. The main aim for this project is to simulate the electric field and potential distribution along dry and clean non-ceramic insulator. Basically, four components have been considered to design insulator, there are metal end fittings, fiberglass rod, silicone rubber sheath and silicone rubber weather sheds. In order to investigate the effect of simplification of insulators on the electric field and potential distributions four model have been designed. They are: (a) two electrodes only, (b) two electrodes and the fiberglass rod, (c) two electrodes, fiberglass rod and sheath on rod without weather sheds and (d) the “full” 34.5kV insulator. The simplified model has been used in investigation the effects of the three phases vs. single phase energization on the electric field and potential distributions. As a result, the study on electric field distribution to simulate high intensity of electric field and potential distribution in electric power apparatus is successfully achieved.
