Electrical system own use is used for various needs in power plant like industry and office, buiding lighting, motor drive, air conditioner, protection system hydran, etc. Generally electrical system own use in PLTP consist of medium voltage 6,3 kV and low voltage 0,4 kV supplied through unit auxiliary transformer, station service transformer and unit service transformer and emergency diesel generator when emergency. With the construction new unit generating that is PLTP unit 4 this time PT. Pertamina Geothermal Energy of Ulubelu have 2 generating units total capacity 110 MW. Because of additional unit of power plant, it is necessary to study of electrical system own use. The purpose is to find out installed own usege transformer can supply the additional loads installed and as a reference for further system.} }
