Abstract: This article is devoted to the feasibility study of an in-tank oil treatment of an operating transformer. This study has been performed with Frontier mine’s ZYD 50 purifier. This purifier operates via filtration, drying and vacuum degassing at a temperature T ranging from 20 ℃ to 80 ℃ with a flow rate of 50 litres per minute. During our study, an identification of the constraints that may occur during a purification of an in-tank oil operating transformer was performed. As a result, the temperature and oil level control of the in-tank oil transformer were found to be the key constraints. Thus, in order to guarantee a safe purification for the transformer within its environment, as recommended by the IEC 60422 standards, we have chosen an HYDAC oil cooler, written a Sequential Function Chart (SFC) for the automation and the safety of the oil purification process. This research makes possible for industry and public sector, the purification of a transformer while connected to the network in order to keep the power supply available while increasing the transformer life.
