Abstract :
In the operation of the voltage value distribution system in each channel point must meet the standard, namely where the voltage (V) operation is limited to 0.9 Vnom ? V operation ? 1.05 Vnom (or + 5% and -10% Vnom) in accordance with SPLN No. 01 of 1995 namely + 5% and -10% of nominal voltage. For feeders in the Sentani area, Depapre Regency, at Gunung Merah a medium voltage network is found that has far below standard voltage as an example Depapre Feeder with a network length of 68.87 km and the voltage received at the Gunung Merah relay station is 19 kV, which causes a voltage drop so there needs to be an improvement analysis. There is a method of repairing the voltage on the distribution network, that is by improving the power factor by adding bank capacitors. The calculation results before the repairs are carried out using a capacitor bank receiving voltage at the end of the depapre feeder is 19201.61 V and the power losses are 13051.8 Watts with a power loss percentage of 1.42%. The calculation results after being done by placing a capacitor bank on the distribution station STN 114 Fisheries Depapre received voltage is 19402.72 V and the power losses obtained at the installation of bank capacitors is 9502,562 Watts with a percentage of power loss of 1.04 %.
