This study analyzes the effect of load variation on power losses at maneuver points within the 20 kV distribution network of the Sambo Feeder, PT. PLN ULP Rivai Palembang. Using ETAP 19.1.0, the research simulates three loading scenarios: light (30%), medium (70%), and high (>80%) to evaluate the impact of rising energy consumption on technical losses and system efficiency. Simulation results f…
