Abstract

The requirement to the response time and dynamic behaviors of a standard impulse resistive divider is very strict. Main influence factor contributes to the measurement error of the divider is caused by stray capacitance to the earth. This paper calculated the stray capacitance and distribution capacitance parameters of the divider´s high voltage arm with finite element method (FEM) and boundary element method (BEM). The simulation results of electric-field and compensation effect on the stray capacitance to the earth with different shield ring structure are analyzed.
