Study of Measurement and Consideration of Energy Sustainment on The Electric Power Distribution System of PT PLN (Persero) ULP Pasir Pangaraian

Abstract

Depreciation is an important discussion at this time because it is related to the quality of power that will be delivered to consumers and opens up potential income for the State Electricity Company (PLN) because the losses that occur in the network will reduce the potential for power sales by PLN. In general, power depreciation can be divided into two types, namely technical depreciation, which occurs as a result of impedance in generation equipment and distribution equipment in transmission and distribution so that there is power lost in the form of heat. power depreciation is impossible to avoid because the equipment cannot have a 100% efficiency level, but what needs attention is whether the depreciation that occurs within reasonable limits. Most of the existing depreciation is suspected to be in the distribution network. From the results of the research that has been done, the results obtained The average load current measured for approximately one month from April to May 2025 shows the highest average load at 14.00, namely Phase R = 405 A, Phase S = 351 A and Phase T = 448 A. The percentage of WBP loading based on connected power from PLN reaches up to 80%. Percentage of Peak Load Time (WBP) loading on the transformer reaches up to 70%.
