Indonesia Power PRIOK POMU}, year={2022}, url={http://156.67.221.169/5136/}, abstract={The failure that generally occurs in the main transformer is a temperature failure or electrical failure. generally produce harmful gases which are commonly known as fault gases. By identifying the type and amount of gas concentration dissolved in the oil, it can provide information on indications of failure in the main transformer. In this final project, the method used to analyze the main condition of the transformer is to use the Total Dissolved Combustible Gas method. The amount of dissolved combustible gas or TDCG (Total Dissolved Combustible Gas) will indicate whether the transformer under test is still in a normal, alert, warning or critical/critical condition. -2008 and the TDCG method that the main transformers GT 1.1, GT 1.3 and ST 1.4 are in condition 1 or an indication that the transformer operation is normal, the next recommended action for the three main transformers is to carry out DGA testing periodically every 3 months. While the Main transformer GT 1.2 from the results of the analysis using the TDCG method states that the condition of the transformer is in condition 1, but the value of ethene gas is in condition 2 according to the IEEE std limit, C57.104-2008 which is around 75 ppm, the recommended action for Main This GT 1.2 transformer is to do a DGA test every 1 month to monitor the increase in the content of ethene gas and perform purification if possible. The gases contained in the transformer oil begin to form at temperatures around 150oC to more than 700oC.} }
