Abstract

Power transformers are one of the most essential and important equipment of the electrical power system, which ensure stable and reliable energy delivery. Transformer operational life depends on its insulation system, which are insulating oil and solid insulating material. The degradation of the insulation occurs as the operating time of the transformer increases. Paper insulation is the most critical component of the transformer insulation system. Experimental and simulation studies on paper insulation showed that temperature, oxygen and moisture contents contributed to its degradation. In this study, level of parameters such as dissolved gases, coil temperature and oil temperature were obtained from transformers in Malakoff Prai Power Plant (PPSB). Then each parameter were differentiate and categorize for end-of-life analysis. The data will be analyse by using Unreliability for a Given Operating Time method in Weibull++ 7 software and Microsoft Excel.
