[Sejalan dengan pertumbuhan industrialisasi, dimana kebutuhan akan tenaga listrikbesar sekali, sehingga generator dapat digunakan sebagai sumber pembangkittenaga listrik.Dalam pengoperasiannya, generator sering mengalami gangguan hubung singkatyang terjadi didalam maupun diluar generator. Gangguan tersebut dapat terjadisetiap saat dan bersifat merusak generator yang dapat mengganggu aliran dayakekonsumen.Akibat yang ditimbulkan tersebut maka perlu diberikan peralatan pengaman untukgenerator, agar gangguan yang terjadi setiap saat dapat diamankan sedini mungkintanpa merusak generator dan apabila generator dihubungkan kesistem tidakmengganggu sistem.Pemilihan rele pengaman untuk generator tersebut didasarkan pada gangguanyang mungkin timbul, yang ditinjau dari situasi dan kondisi setempat, sehinggasetelah dihitung didapat peneyetelan rele diferensial dengan batas ambang 0,16 Adan rele arus lebih 0,96 A dengan waktu 2 detik , rele gangguan tanah stator 0,17A, rele daya lebih 144 watt rele tegangan lebih 121 Volt, rele beban tak seimbang0,94 A dan 12,4 detik, rele kehilangan medan 1,2 Ohm dan diameter kerja 9,7Ohm dan rele daya balik disetel -2,34%;In line with the growth of industrialization, where the demand for power isenormous, so that the generator can be used as a source of power generation.In conducting the operation, the generator often experience short circuit thatoccurred within and outside the generator The disorder can occur at any time anddestructive generator that can disrupt power flow to consument.With the impact that it should be given safety equipment to the generator, so thatdisturbance at any waktu can be secured as early as possible without damagingthe generator when the generator is connected to a system and do not disturb thesistem.Selection of safety relays for the generator is based on problems that may arise,which in terms of local circumstances, so that can know what amount of theamount of influence in the disorder, which scale is used to determine the amountof setting. So that after calculation ,relay differential threshold setting is 0,16 Aand overcurrent is 0,96 A with time delay 2 s,stator ground fault relay 0,17A,Overload relay 144 W, Overvoltage 121 V, Load Unbalance relay 0,94 A and12,4 s, Loss of Excitation relay 1,2 Ohm and diameter 9,7 Ohm and ReversePower Relay is setting -2,34%, In line with the growth of industrialization, where the demand for power isenormous, so that the generator can be used as a source of power generation.In conducting the operation, the generator often experience short circuit thatoccurred within and outside the generator The disorder can occur at any time anddestructive generator that can disrupt power flow to consument.With the impact that it should be given safety equipment to the generator, so thatdisturbance at any waktu can be secured as early as possible without damagingthe generator when the generator is connected to a system and do not disturb thesistem.Selection of safety relays for the generator is based on problems that may arise,which in terms of local circumstances, so that can know what amount of theamount of influence in the disorder, which scale is used to determine the amountof setting.
