Impact Analysis of Asymmetric Conditions on an Oil-Filled Distribution Transformer Performance

This paper shows the results obtained from the simulation of a study case about the impact of asymmetric operational conditions on oil-filled distribution transformer useful life. The results depend on the supplied energy level through three different demand profiles (unbalance) mixed with two asymmetric conditions (no asymmetric condition and two additional cases with different asymmetric conditions). The disturbance analysis is realized through the FBD and symmetrical components theories, in order to obtain an equivalent factor to the , which will be used to characterize the transformer loss of life from the temperature rise in the transformer (oil).  Finally, it is realized a discussion about the results obtained and the possible analysis field for future studies of this topic (asymmetric conditions).
