Analisa Perbaikan Drop Tegangan JTR dengan Menggunakan Metode Trafo Sisip dan Uprating Kabel Berbasis Simulasi ETAP 12.6.0 di PT. PLN (Persero) UP3 Lubuk Pakam ULP Perbaungan

The electrical system in Kenari Hamlet is supplied by the PR 072 distribution transformer through PU.08 feeders. The PR 072 transformer is located on Jalan Melati, Desa Melati II with a capacity of 160 kVA which is used to supply electricity to the Dusun Nangka area. Based on the results of the measurements that have been made, it is found that the low voltage value in the Dusun Nangka area is 170 volts against the one-phase source voltage to neutral (226 V) and occurs during peak loads or in other words the voltage drop. According to SPLN 1: 1995, the service line voltage tolerance (SP) is + 5% of the standard low voltage stress at the base side and -10% at the end side. At 19.00 when there is a peak load, consumers cannot make electronic devices such as water pumps, refrigerators, air conditioners and others. With such conditions, it is necessary to simulate ETAP 12.6.0 to make improvements, namely the construction of an in-line transformer and uprating the HUTR 3x35mm2 + 1x25mm2 to 3x70mm2 + 1x50mm2 in that area. For this reason, several assumptions are made, namely direct measurement calculations and simulations so that the low voltage value in the area is 219 Volts.
