Monitoring the temperature of a power transformer has a crucial role to keep it's good performance, prolonging its lifetime, as well as, ensuring stability of the whole electric system. In this paper, we've estimated the top-oil temperature and the coil hotspot. A fuzzy logic-based methodology was developed leading to satisfying results compared to the IEEE-C5791 model. A significant accomplishment, since this method could provide monitoring with better precision, in a simpler way, without the need for short-circuit tests and internal transformer data, allowing companies and engineers to perform upfront maintenance in the substations equipment’s.
