ABSTRACT In today's highly competitive industry, manufacturing and production industries are required to always be ready and reliable in the availability of products offered to consumers. This is absolutely absolute because ultimately it involves consumer satisfaction as the final part of a business chain. One of the factors that plays an important role in the industrial world is the facilities and facilities, facilities and facilities including production machinery, buildings, materials, and other supporting facilities. In this case the production machine is a vital part in a work / manufacturing location, where the production machine generally uses an electric motor as a driver in operating it. One type of electric motor that is widely used is the type of commutator induction motor, because according to their needs, namely for high speed, such as drilling machines, planers, mixers, which are the driving force of workshop and production equipment, which are often used in frame making workshops, workshops lathe, and other workshop. On continuous operation, only a few seconds of operation will stop, the motor coil will heat up, which means expansion of the coil wire. This will result in changes in motor impedance, so that the motor rotation will also change. The provisional guess of the test is that there is a expansion of coil wire due to heating, which results in an increase in motor impedance, so that the motor rotation will decrease
ABSTRAK Panel LVMDP merupakan peralatan listrik yang terdiri dari beberapa komponen listrik, yang berfungsi sebagai pembagi utama saluran distribusi tegangan rendah ke setiap saluran beban, sebagai pembatas daya utama, dan pengaman pada rangkaian utama sistem distribusi tegangan rendah. Komponen-komponen yang terdapat pada panel LVMDP ini antara lain, MCCB utama, MCCB salauran setiap beban atau cabang, Selector Switch, Contactor, KWh meter, ACB, UVT, OVT, OCR, EFR, RPR, GFCI, RCD, TOR, Busbar tembaga, CT, Alat ukur arus, tegangan, frekwensi, Faktor kerja, Synkronous meter, Capacitor Bank, Pushbutton, Pilot Lamp, dan peralatan penunjang lainnya, seperti terminal, dan lainnya. Komponen utama yang sangat berperan dalam penyaluran daya suatu panel LVMDP dalam keadaan normal adalah MCCB, yang dapat memikul seluruh beban panel dalam keadaan steady state. MCCB ini akan ditunjang oleh komponen-komponen lainnya apabila terjadi gangguan, seperti bila terjadi hubung singkat, yang terjadi setelah MCCB. Bila terjadi gangguan sebelum MCCB, maka komponen yang akan bekerja adalah UVT atau OVT, dan seterusnya, sehingga bila terjadi gangguan maka MCCB akan di backup oleh komponen penunjang. Tetapi bila terjadi kegagalan pada komponen penunjang, maka MCCB harus dapat berfungsi sebagai proteksi terhadap panel LVMDP secara keseluruhan, baik dari gangguan beban lebih, maupun gangguan hubung singkat, tetapi MCCB tidak dapat menanggulangi gangguan di luar kemampuannya. Dengan demikian kemampuan MCCB untuk melindungi panel LVMDP dari gangguan beban lebih dan hubung singkat, tertera pada nameplate MCCB tersebut.
