Thermal behaviors of transformers have a close relationship with the ageing processes of transformer insulation. In oil immersed transformers, feature temperatures such as top-oil temperature and hot spot temperature are recommended to be monitored online. To minimize the risk of failure and to extend the serving life time of transformers, both temperature rises should be controlled within certain range. However, it is difficult to monitor the hot spot temperature of the transformer. Commonly… CONTINUE READING
