Journal Increasing System Reliability Through Repairing the S phase Hotspot Clamp in Circuit Breaker in the Reactor Bay of the Nagan Raya Substation

Abstract

Electrical installation equipment is always exposed to factors that cause its condition to deteriorate, such as physical/mechanical, chemical and environmental contact. The factor used as a reference for inspection is the temperature of the operational equipment. Unnatural temperatures will be produced by electrical equipment because electricity is energy that produces heat and worsens the condition of the equipment, so infrared cameras play a role in monitoring the condition of electrical equipment using the temperature of the equipment as a reference. The Thermovision method is a remote monitoring of the temperature conditions of substation equipment when under load to determine the hot temperature of the clamps and conductors and the difference between the two. This journal discusses the repair of hot spots found in the reactor bay Circuit Breaker equipment at the Nagan Raya Main Substation with a temperature of 85.3°C. Temperature standards in determining equipment condition are in accordance with SPLN SK DIR/No.520/2014. Thus, the results of measurements using conductor thermovision in the reactor bay can be used as a reference for preparing further maintenance recommendations.
