Design of low voltage main switchboard 415240v for electrical power distribution system in commercial building_Saiful Azhar Abdul Rahim_E3_2006_NI
Projek ini mengemukakan rekabentuk sebuah Papan Suis Utama Voltan Rendah (415/240V) dalam sebuah bangunan komersial dengan tujuan untuk mengagihkan kuasa elektrik yang diperlukan oleh beban beserta sistem perlindungan. Objektif utama projek ini ialah merekabentuk Papan Suis Utama Voltan Rendah termasuk Sistem Tunggu Sedia (Penjana Diesel dan Bekalan Kuasa Tanpa Gangguan), Sistem Perlindungan Kebakaran dan Sistem Televisyen Antenna Satelit Utama.. Selain, projek ini memberi lebih pemahaman tentang peralatan elektrik seperti pemutus litar, sistem bus yang digunakan dalam Papan Suis Utama, peranti perlindungan arus berlebihan dan arus bocor ke bumi dan lain-lain peralatan elektrik. Rekabentuk projek bermula dengan pengiraan jumlah keseluruhan data beban dimana permintaan maksima P = 850 kW, arus keseluruhan, I = 850 A dan voltan perkhidmatan, V = 415 V (Voltan Rendah). Dengan maklumat yang diperolehi daripada pengiraan data beban, hasilnya ialah kita boleh menentukan saiz kabel utama, pemutus litar utama, peralatan mengira dan meter beserta lain – lain peralatan elektrik yang terdapat didalam Papan Suis Utama. Untuk merekabentuk sistem yang lebih baik, kajian mengenai projek ini harus dijalankan dengan lebih mendalam di masa hadapan. ______________________________________________________________________________________ This project emphasizes the design of Low Voltage Main Switchboard (415/240V) in commercial building with the purpose to distribute electrical power to the load together with protection system. The main objective of this project is to design a Low Voltage Main Switchboard consists of Emergency Standby Supply (Generator set and Uninterruptible Power Supply), Fire Protection System and Satellite Master Antenna Television (SMATV). Besides that, this project give a clear understanding about electrical equipment such as circuit breaker, busbar system used in Main Switchboard, protection relays such as overcurrent and earth leakage protection and many others equipment. The project design starts with load data calculation where maximum demand P = 520 kW, total current I = 850 A and voltage supply V = 415 V (Low Voltage). With thi information we get from the load data calculation, the result is we can size up the main cable, main circuit breaker, metering and measuring instrument, and others equipment include in Main Switchboard. For future work, more research could be done in this project in order to design a high efficient system in electrical power distribution.
