Analisa Proteksi Auto Recloser pada Sistem 150kV Penghantar Menggala – Gumawang 2 Di Gardu Induk Menggala

Abstract

Auto Recloser (AR) is one of the 150 kV SUTT safety equipment that functions to anticipate momentary disturbances so that power outages can be anticipated, so that the outage area does not expand so that the continuity of power distribution remains reliable.This research was carried out by collecting data from the Menggala Substation and about Auto Reclose to be able to find out what Auto Reclose is, how the working principle and settings of Auto Reclose, what are the components of Auto Reclose and what is related to Auto Reclose, then the data attached to the gumawang 2 conductor is analyzed, from the results of the analysis is expected to be used as a reference in conducting Auto Restore settings. Based on the results of this study, Auto reclose relay is applied to gumawang 2 conductors using TPAR (Theree Phase Auto Reclose) type system settings and adding Zero Voltage Relay (RTN) to the 1#30 MVA transformer protection mini substation with time setting the same as distance Zone 1, namely 0s / Instant, so as to avoid auto energize on the transformer at the Mini Substation.
