Indonesia Power UJP Labuan. The protection system serves to protect the electrical power system, its surrounding operators, and the equipment itself from various interferences that may occur. In power plants the main equipment is a generator that serves to convert mechanical energy into electrical energy. PLTU Banten 2 Labuan has 2 units with a capacity of 600 MW. generator that being used is product from dongfang electric machine 300 MW. To maintain the reliability of the work of the generator, the generator is equipped with protection equipment. Generator protection equipment must prevent generator damage, because the damage generator in addition to expensive repair costs are also very disturbing the operating system. One of the relay that work on a generator is a differential relay, because the nature of these relay works uncoordinated with other relay. The differential relay is used as the primary safety of the generator. Therefore it is necessary to setup the differential relay on the generator. Differential relay settings obtained by 22,5%. Obtained the results of a differential minimum current calculation of 0.1698 A. In the calculation of the 3 phase short circuit current obtained at 11.309 kA.} }
