Power loss in the power distribution system is computed with “ETAP” simulation software. From computing result of distribution network losses on existing line at PT. PLN UPJ. Bantul BNL 6, BNL 7 and BNL 11 feeders are gotten energy losses as 2,669,328 kWh per year or %. Network reconfiguration that involves BNL 6, BNL 7 and BNL 11 feeder gets energy losses decrease as % per year. | Calculation of 20 kV distribution network energy losses and minimizing effort using network reconfiguration in region of PT PLN Persero UPJ Bantul
