Developing a framework to conduct ageing studies in Insulating Oil for Power and Distribution Transformers

Due to significant dielectric properties of Mineral Oil (MO) it has been used as an insulating oil in Power Transformer (PT) and Distribution Transformer (DT). The critical functions of the insulating oil dies as it ages and needs to be replaced periodically. The ageing of insulating oil gives data that can be used to develop predictive model. With the use of predictive model one can predict the deterioration rate of an oil. The ageing model or predictive model requires a framework to streamline the ageing test on oils. The method is overwhelmed by various ideas of ageing model adopted from previous literature. Upon using the ageing framework, the new ageing method and standards can be developed in future. Hence, the review catapulted the designing of new ageing model to predict the deterioration of oil under transformer environment.
