Voltage drop at the feeder end is one of the problems that often occur in electrical power distribution
systems, especially in networks with increasing loads. This study aims to analyze the power losses
and the relationship between load conditions, network length, and the ability of the substation to
maintain the voltage profile at the AE005 Substation of Golewa Feeder, ULP Bajawa. The analysis
method used technical calculation of power losses, evaluation of load currents, and simulation of
voltage profiles under several operating conditions to identify the dominant factors causing voltage
drops. Based on the measurement results, the AE005 substation experienced a transformer load of
127.99% and a voltage drop of up to 22.9%, exceeding the standard limit of SPLN No.72:1987 which
allows a maximum drop of 4%. To overcome this, a load breakage strategy was carried out to the
AE023 substation with a capacity of 25 kVA. The results of the analysis showed that after the load
break, the load of the AE005 transformer dropped to 67.62% and the AE023 increased to 81.88%,
while the maximum voltage drop value dropped to below 5%. Thus, load breakage has proven to be
effective in reducing power losses and improving voltage quality in the distribution network.
