Pada zaman moden, bekalan elektrik merupakan suatu keperluan asas yang penting untuk keselesaan pengguna, tanpanya insfraktrutur sosial tidak akan dapat dilaksanakan.
Pertambahan penggunaan bekalan elektrik per kapita di seluruh dunia menggambarkan pertumbuhan taraf kehidupan manusia yang semakin meningkat.Penggunaan optimun tenaga ini hanya dapat dijamin melalui sistem pengagihan yang efektif. Kuasa daripada sistem pengagihan ini diagihkan kepada pengguna melalui penyalur kuasa, pengagih dan servis utama. Penyuap mengkonduk arus yang besar secara pukal dan pengagih merupakan konduktor dan arus seterusnya dibekalkan kepada premis pengguna. Disebabkan voltan yang rendah, arus yang besar, kehilangan kuasa dalam sistem pengagihan adalah lebih tinggi berbanding kehilangan kuasa dalam sistem pencawan voltan tinggi. Peningkatan kecekapan secara keseluruhannya oleh kuasa pengagihan akan mentebabkan berlakunya kehilangan kuasa, terutamanya pada peringkat pengagihan. Kehilangan kuasa dalam sistem pengagihan dapat dikurangkan melalui konfigurasi semula rangkaian. Sistem ini akan mengubah aliran kuasa dari sumber kepada beban. Sebuah program telah dibina berdasarkan program MATLAB untuk menjalankan analisis di dalam laporan ini. Prestasi kaedah yang dicadangkan telah diuji pada sistem pengagihan yang mengandungi 33 bas dan didapati bahawa penjimatan kehilangan yang tinggi boleh dicapai dengan menggunakan Sistem Pengagihan Voltan Tinggi.

Electricity is modern society’s most convenient and useful form of energy. Without it, the present social infrastructure would not all be feasible. The increasing per capita consumption of electricity throughout the world reflects a growing standard of living of the people. The optimum utilization of this form of energy can only be ensured by effective distribution systems. A distribution system is the one from which the power is distributed to various consumers through feeders, distributors and service mains. Feeders are conductors of large current carrying capacity carrying the current in bulk to the feeding points. Distributors are conductors from which the current is tapped off the supply to the consumer premises. Because of lower voltage, and hence higher current, the I2R loss in the distribution system is significantly high compared to that of a high-voltage transmission system. The pressure of improving the overall efficiency of power distribution has forced the power utilities to reduce the loss, especially at the distribution level. The I2R loss in a distribution system can be reduced by network reconfiguration. The reconfiguration changes the path of power flow from source to the loads. A program has been developed based on MATLAB program to do the analysis in this project.The perfomance of the proposed method was investigated on distribution system consisting of 33 buses and it was found that a significant loss saving can be achieved by using a of High Voltage Distribution System
