Analysis of Abnormal Hotspot Repair on the 500kV South Bandung – Mandirancan Transmission Line T.168 Using the Ohmstick Plus Live-Line Maintenance Method

Abstract

The transmission system has the role of connecting generation centers with population growth centers. In the operation of the transmission system, it is not free from various disturbances and anomalies that can damage the reliability of the electricity distribution system. Hotspots are temperature abnormalities that occur in equipment that is powered by electric current, generally occurring at the connection point. Hotspots can cause losses because electrical energy is converted into heat energy at the point where the hotspot occurs. Hotspots can also cause equipment damage because they melt due to heat. Repair of hotspots that occur in conductor jumper clamps & link adjusters on SUTET 500KV South Bandung – Mandirancan (BDSLN-MDCAN) T.168 ARAH 167 FASA R. In this case it can be seen that a hotspot has occurred at an abnormal point. The point in question is the link adjuster, where this component functions to connect the yoke with the conductor to obtain the desired saging. The normal condition of the link is that there is no current so hotspots will not appear. OhmStick Plus is an instrumentation tool for measuring current and resistance in a connection directly and at voltage. So it will help describe the sequence of work points and serve to justify normal conditions after repair of the hotspot. The advantage gained when repairing hotspots using the PDKB method is that there is no need to wait for a scheduled power outage, especially when the anomaly status falls into the emergency category.
