Litar pintas merupakan masalah yang biasa berlaku di dalam sistem elektrik kuasa. Terdapat beberapa faktor berlakunya masalah ini antaranya adalah disebabkan kegagalan penebatan antara talian fasa dan bumi. Arus berlebihan yang tinggi disebabkan litar pintas mampu merosakkan peralatan elektrik sekiranya sistem perlindungan yang sesuai tidak dipasang di dalam sistem kuasa. Oleh kerana itu, sistem perlindungan lebihan arus memainkan peranan yang sangat penting terutama dalam memastikan keselamatan peralatan elektrik di dalam sistem kuasa. Tujuan yang sama juga akan digunakan di dalam eksperimen untuk menentukan tahap nyah cas bagi minyak kelapa sawit sebagai penebat cecair di dalam sistem voltan tinggi. Di dalam projek ini, tujuan utama adalah untuk memastikan keselamatan operator makmal semasa menjalankan eksperimen selain melindungi radas-radas makmal daripada rosak sekiranya berlaku arus lebihan seperti litar pintas. Untuk mencapai objektif projek, beberapa spesifikasi sistem dipertimbangkan sebelum litar bagi sistem ini dilakar. Seterusnya operasi bagi sistem ini akan dianalisa dengan menggunakan PSCAD. Setelah selesai, beberapa ujian terhadap komponen di dalam sistem akan dilaksanakan untuk memastikan komponen berada di dalam keadaan yang baik. Akhir sekali, sistem perlindungan arus lebihan ini akan ditauliahkan dan faktor-faktor yang menyumbang kepada kelemahan sistem akan dibincangkan. _____________________________________________________________________________________ Short circuits and other abnormal conditions often occur on a power system. It occurs due to the failure of the insulation between a phase conductor and the earth, or due to a phase conductor breaking and falling to the ground. The heavy current associated with short circuit is likely to cause damage to equipment if suitable protection system is not provided. Therefore, in this case an over current protection plays an important role to avoid the power system from malfunction. The same concept of the over current protection will be used in an experiment to determine a level of partial discharge for palm’s oil as liquid insulator in high voltage laboratory. In this project, the main objective is to ensure the safety of the lab’s operator during conducting an experiment and also to protect the equipments in laboratory from damage due to fault especially short circuit. Before design the circuit, all requirements needed in the system are considered. Then, the operation of the system is showed graphically by using PSCAD before the hardware is implemented. Finally, the commissioning of the protection system is done solely and the factors which may affect the ability of the system are discussed.
