The Optimization of Grading Ring Design for 800 kV UHVDC Transmission Lines

July 19, 2021

ABSTRACT: The three-dimensional finite element method is used to calculate the electric field of insulator strings for ±800 kV UHV DC transmission lines. After the comparison of electric field distribution and voltage distribution with different ring diameter, tube diameter and shielding depth, the dimension and position of grading ring is recommended. The ball-gap method is …
