    Abstract:

    110 kV flashover limiter has two kinds of installation method depending on the lower discharge electrode installed lower or higher than grading ring. In this paper, a finite element model is established for a 110 kV doublecircuit transmission line and the influence of installation type for the electric field distribution of glass insulator and grading ring is compared. It is shown that the lower electrode which is installed lower than the grading ring reduces the uniformity of electric field along the glass insulator, whereas the other installation method uniform the electric field along the glass insulator. Both two types of installation reduce the electric field at the outer surface of the grading ring. It is better that the lower discharge electrode is installed higher than grading ring when installing 110 kV flashover limiter on glass insulator.
