Abstract

Listrik merupakan salah satu komoditi strategis dalam perekonomian Indonesia, karena selain digunakan secara luas oleh masyarakat terutama untuk keperluan penerangan, listrik juga merupakan salah satu sumber energi utama bagi sektor industri. Susut energi pada jaringan merupakan masalah utama PT. PLN (Persero) Distribusi Jawa Barat dan banten Rayon Majalengka. Upaya yang dilakukan untuk menurunkan susut adalah memperbaiki jaringan yang ada dan menekan susut non teknis akibat pencurian listrik. Energi listrik yang hilang dalam perjalanan penyaluran energi listrik baik di saluran transmisi maupun ditsribusi disebut dengan rugi-rugi atau susut enrgi teknis. Sedangkan susut energi non teknis berkaitan dengan pengukuran energi listrik di sisi pelanggan. Besar susut teknis pada penyulang Jatiwangi adalah 195,01 kW, sedangkan besar susut non teknisnya adalah 445, 96 kW. Susut tahunan pada Penyulang Jatiwangi adalah 3.505.541,85 kWh. Perbaikan Losses dengan cara menaikan tegangan 1 kV didapatkan arus sebesar 214,89 ampere yang sebelum nya adalah 225 Ampere. Perbaikan Losses pada jaringan SUTM Susut konduktor berkurang sebanyak 29,77 kW yang sebelumnya adalah sebesar 161,27 kW.

Abstract

Three-phase induction motors are the most widely used type of motor in industry, induction motors are widely used as prime movers to turn loads on production machines in the industrial world. The output of a three-phase induction motor is the amount of torque to move the load. If the load torque carried by the three-phase induction motor is greater, then the three-phase induction motor will not rotate. And if the load torque carried by a three-phase induction motor is too small, this is considered excessive. In this analysis the method used by the author is the experimental method of analysis using the Power Simulator application with load data and induction motor data. Based on the analysis, it was found that Istart and Inominal on a 15 kW induction motor have different values ​​according to the torque value used, so the torque value is directly proportional to the Istart value. Meanwhile, Istart induction motors 15 kW 894.324 (15 N.m), 894.149 (25 N.m), 894.159 (60 N.m) and 45 kW induction motors 355.15 (25 N.m), 355.172 (60 N.m), 355.172 (80 N.m) and induction motors 55 kW 337.743 (30N.m), 337.76 (50N.m) and 337.761 (100N.m) Reaches 80% of full speed, torque is at its highest “pull-out torque”) and current starts to fall and is at full speed, or synchronous speed, torque and stator currents drop to zero, it can be concluded that the greater the value of the stator resistance, the smaller the value of the starting current.

Abstract

At PT PLN (Persero) Indramayu Customer Service Unit, it was recorded that electrical energy supplied from the substation at PT PLN (Persero) Indramayu Area in 2019 was 347,133,287.9 ​​kWh, while the energy sold was 312,676,929 kWh and the amount of energy losses of 34,456,358.9 kWh.[5] The difference in the amount is due to energy losses or losses. Energy losses are the amount of energy lost in the energy flow process from the substation or distribution substation to the consumer. This is caused by two factors, namely technical and non-technical factors. Technical factors caused by distribution network problems. The study carried out was a study of energy loss on feeders, namely the Lohbene feeder, this name is an aid to the name of the feeder from ULP Indramayu. The object specification data for this study were obtained based on data from ULP Indramayu and the Indramayu Service Unit. After conducting the research, it can be concluded that the technical losses in the Lohben feeder are 1120.94 kW, while the non-technical losses are 189.96 kW. The annual losses in the Lohben feeder are 8,315,678.42 kWh. reduced to 482.69kW, which was previously 875.486kW. After technical improvements, losses decreased to 406.430 kW per month
