At PT PLN ULP Warujayeng, there was Warujayeng Feeder with load current of 159 A during normal condition and 297 A when the peak load also voltage drop reaches 7,14%. There was also Kalianyar Feeder with a load current of 163 A under normal condition and 254 A when the peak load and voltage drop reaches 6,28%. It can be seen that the value of the voltage drop was close to the standard set at -10% and +5%. To overcome this problem, PT PLN has transferred some of the load on the two feeders to a new feeder called the Mojokendil Feeder. It was carried out by cutting the Banjarsari LBS at the Warujayeng Feeder to function as the Banjarsari Recloser for the Mojokendil Feeder then cutting the Kalianyar Feeder and Warujayeng Feeder to be connected to the Ngetrep LBS which was previously an asset from the Kalianyar Feeder. In addition, the ten pole transformer substations at the Warujayeng Feeder and forty-four pole transformer substations at Kalianyar Feeder are designated for the Mojokendil Feeder. Based on the analysis after reconfiguration, it was found that the load decreased by 87,81 A on the New Kalianyar Feeder; 121,21 A on the New Warujayeng Feeder, and there is 110,9 A on the Mojokendil Feeder. The voltage drop precentage was decerased by 2,278% in the New Kalianyar Feeder, in the New Warujayeng Feeder is 2,32%, and also in Mojokendil Feeder 2,87%. So, this additional feeder is very effective in improving network performance © 2023 IEEE.
