The Analisa Jatuh Tegangan Pada Sistem Jaringan Tegangan Menengah Pada Penyulang Bupati Polres Di PT PLN (Persero) ULP Sentani

Voltage Drop Analysis of the Medium-Voltage Distribution Network on the Bupati Polres Feeder at PT PLN (Persero) ULP Sentani

Abstract

The increasing demand for electrical power necessitates reliable distribution systems, where voltage drop is a critical parameter affecting power quality. This study analyzes the voltage drop on the Bupati Polres Feeder at PT PLN (Persero) ULP Sentani to ensure network performance remains within permissible limits and to identify critical points. The analysis was conducted using a dual approach,  manual calculations based on technical data and SPLN standards, and simulation using ETAP software to validate the results. The total voltage drop obtained was 207.726 Volts (1.03863%), which remains below the PLN tolerance limit of 5%. The point with the highest voltage drop was identified at Bus 7, which functions as a main branching point. Although the overall performance meets the standard, Bus 7 is a critical area requiring special attention through load redistribution, review of transformer spacing, and regular network maintenance to minimize future voltage drops.
