Abstract	Future developments of end corona protection (ECP) systems require calculation of the electrical field strength along the insulating surface and the temperature profile with satisfactory accuracy. This report presents an approach for the exact calculation of relevant physical parameters for a typical ECP configuration based on the finite element method, this approach accounting for the large electrical nonlinearity as well as the weaker thermal nonlinearity of the ECP material. The peculiarities of the implemented calculation algorithm for modeling the electrically and thermally coupled system are presented and the function of the model is verified based on practical tests which confirm the extremely good correlation between the calculated and measured results.
