To support the continuity work of load equipment from high effectifity generating electrical power system at 50.000 DWT “MV. LARCH ARROW” vessel it necessary to have of controlled electrical system that consist of electrical devices and protecting devices with technical specification and working properly to avoid many kind of disturbances permanently or temporer that caused by abnormal condition like over current, reverse power, under voltage and another fault such short circuit and overload. That need to have studying and analyzing about electrical system at 50.000 DWT “MV. LARCH ARROW” vessel for electrical devices and protecting devices that giving guarantee the quality of generating electrical power system.Keywords:Electric power station, Electrical system, Disturbances, Protecting devicesBambang Riyanto, Kotima, Rony Yuliono; urusan Teknik Elektro – ITATS
