Abstract :
he transmission line has the greatest impact in the event of a disturbance, because it breaks the continuity of the load distribution. Therefore, efforts are needed to reduce the effects of these disturbances. Disturbances that often occur in transmission networks such as hotspot anomalies at clamp connection points or conductor connections. If it occurs continuously continuously can damage the connection or equipment. The biggest impact that will occur is the connection will be broken or melted and there will be disturbance to the ground. To prevent the occurrence of hotspot anomaly disturbances, routine maintenance is carried out to determine the temperature at the connection points or clamps by means of thermovision. Thermovision is an instrument for visualizing and detecting the temperature of an object that is captured and displayed on a display with technology. The tool used to perform the thermovision test is a VisIR 640 branded device. On the 500 kV SUTET network on the Cilegon-Cibinong route towards GITET Cilegon there is a hotspot anomaly. Based on the known data, the t in the S phase shows 53.02 in the direction of GITET Cilegon. According to the table of efforts and thermovision testing, if the value is > 30 , repair or replace immediately for a maximum of 1 week. Repairs carried out by replacing the bolt and nut material due to the material being dirty, loose and corroded. Based on the calculation of the losses achieved when the gannet type ACSR conductor reaches the melting point so that there is a breakdown of around Rp. 79,823,077,698,312. Based on the multiplication between the radiation heat transfer equation and the price per kWh, it is Rp. 1,644.52, which in 2020 the price per kwh is high, the value is very small at Rp. 7,302.
