Abstract

Finite element method is applied to the calculation of voltage distribution along composite insulator strings of 500 kV transmission lines

and the result is applied to position optimization of grading rings.3D electrostatic model is established and grading rings

bundle conductors

cross arm are considered.The length of exterior boundary is discussed and suitable length is selected.The voltage distribution of several position combinations of the two grading rings is calculated and compared

and the best position combination is selected.
