Abstract: Frequent failures of transition joints were reported mainly near to the crutch area of the paper insulated cable side of the joints. In this paper, the authors present an estimation of the electric field and temperature distribution in the paper insulated cable side of a transition joint using simulations based on finite element method for 3-D geometry, which, apparently did not get much attention until now. It is found that non-linearities in material properties result in drastic changes in the distribution of electric field. The results indicate electric field enhancement near crutch area. The effect of varying load current, and ambient temperature on the peak electric field has been investigated. The simulations are validated analytically. The results are considered important for utilities and manufacturers.
