In this study, the analysis for the correlation between the creepage discharge of transformer pressboard and the amount of dissolved gases in the oil and the furanic products has been performed. As a result, it was confirmed that a large and small discharge was concurrently generated until the tracking (carbonization) phenomenon on the pressboard occurred. It is found out that two kinds of process may exist in the correlation between the accumulated partial discharge quantity and the dissolved gas in oil, depending upon discharge pulse magnitude and the generating rate. The ‘fast process’ in which the average discharge pulse magnitude is large and the generating number per second (rate) is big, whereas ‘slow process’ is vice versa. According to the process, the dissolved gas in oil became different. In addition, the generation of CO gas was small during the tracking (carbonization) phenomenon of the pressboard, but there was a correlation with accumulated discharge quantity. On the contrary, CO₂ gas showed no correlation with accumulated discharge quantity. The correlation between the accumulated discharge quantity and the furanic product was very weak, but it is confirmed that 5M2F which is a result of local overheating showed some correlation.
