Analysis of Energy Losses in Medium Voltage Networks (20 Kv) at Numfor Airport Papua
Keywords:
Losses, Medium Voltage Network (20 kV) at Numfor AirportAbstract
In general, an electrical power system consists of four main components, namely power plants, distribution networks, transmission networks, and loads. The distribution process has several problems, one of which is power loss. The cause of this loss is resistance in the conductors and the distance to the load being too far, resulting in power loss in the conductors. This study aims to calculate the power losses that occur and to calculate the energy losses and financial losses that occur during peak load. In this study, the method used is a quantitative approach where data collection is carried out through literature studies, observations, and direct interviews. The results of the study show that the amount of power loss that occurs in the 20 kV high voltage transmission line during peak load for one month is 10.20204 kV. The amount of energy loss in the MPH transmission line to substations 3, 2, and 4 in one month was 122.42448 kWh, with financial losses borne by Numfor Airport in Papua in January 2025 amounting to IDR 190,207,242. From the results of the total rupiah electricity tariff in January 2021 amounting to Rp 1,171,777,914 compared to the total power loss of Rp 190,207,242, the loss incurred by Numfor Papua Airport was 16.2%
