摘要
This paper gives an overview about comprehensive investigations and analysis on the stress grading system of a 20 kV rated voltage hydro bar. This includes relevant electrical and thermal calculation results of 3 different FEM-models to assess the efficiency of the stress grading system. Further investigations show sufficient correlation of calculation results with measurements conducted in the laboratory.
