Analisis Drop Tegangan Listrik Menggunakan ETAP Pada Penyulang Utari PT. PLN (Persero) Unit Layanan Pelanggan Bandarjaya

Abstract

Voltage drop is the loss of voltage caused by several factors. PLN sets the standard of voltage at +5% -10% of the line voltage. The Utari feeder experiences a voltage drop caused by the length of the network plus the amount of load that is concentrated at the end of a network. This study uses observation method or library research. The source of the data used is secondary data (which already exists) which is then simulated using the ETAP application by utilizing the Load Flow Analysis function so that the results of the power flow in the electrical system are obtained. Based on the results of the study, to increase the voltage by building an underbuild network. The construction of this underbuild network aims to cut the length of the Utari feeder which is then maneuvered into Gunung Madu Plantation feeder. The voltage which was originally 17.217kV to 18.968kV with a difference is 1.751kV, namely there is an increase in voltage of about 7.4% from before. With the breaking of the load, it can shorten length of the feeder, so that by reducing the length of the feeder, the inductive reactance of the line will decrease so that the shrinkage is smaller.
