Abstract :
Population growth has made an increasing impact to the sector of housing development in Jayapura city, it?s also causing the demand for electrical energy also increases. To solve these problems, it?s necessary to make a planning on low voltage network system. this planning was made at Mawar Saron housing Jayapura. A planning can be said good, if the plan can be applied for a long period by considering the load growth factor that could happen in the future. From the research, it requires 132,800 VA total power to provide customer needs in the Mawar Saron housing. The costumers can be divided into two types, which is type 36 with 2200 VA power demand for 32 units and type 21 with 1300 VA power demand for 48 units. So, the capacity of transformer that be used is 250 kVA with 53.12% of loading percentage and the type of substation that be used in this planning is a portal substation. The conductor that be used is NFA2X-T 3x95+70 mm2 with 4 rods of type TR-6 pole, 10 rods of type TR-1 pole, and 4 rods of type TR-3 pole. 9 meters is the height for each pole and 40 meters is the distance between each pole. So, the length of the conductor from transformer to the farest pole is 280 meters long. the amount of drop voltage value in the system is 8,5 V (2,2%). With these results, the voltage drop value can be said very good. Because according to SPLN 1:1995, the drop voltage values that can be allowed is +5% and -10% of its nominal voltage.
