Abstract :
Voltage drops and power losses always occur in an electric power system, especially in the distribution network. PT PLN (Persero) issued SPLN No. 72 of 1987 as as a reference of tollerated limit, so that it can determine wheter the distribution network is reliable or not, the Barito Feeder is one of the feeders from the CSW switch yard which has a 7.511km channel length, 11 distribution substations and uses underground cable channels, with NA2XSEBY cable type. The barito feeder was chosen as the object of research on voltage drop, and power losses since it has the largest load within all feeders on the CSW switch yard. Following the results of manual calculations performed using data consisting of transformer measurements at each barito feeder, the total value of power money was 58,710 kW (1,774%) and the amount of losses related to Barito deviations was 789,840 V (3,949%), according to SPLN No.72 of 1987 the permitted voltage drop is 5%, thus the Barito Feeder is still within the barito feeder limit.
