What is it about?
For HFPT insulations, surface discharge is a serious problem. Polyimide (PI) is a widely used insulating material for HFPT’s. We studied surface discharge phenomenon on Polyimide.This paper first time used the fluid-kinetic model by adopting the finite element simulation method to address the micro-level study of surface discharge. This paper aimed at the discharge phenomenon of the PI under the direct action of high-frequency sinusoidal voltage.

Why is it important?
There is no prominent study with high-frequency sinusoidal voltage, so this paper studied the numerical simulation of surface discharge over PI insulation of the HFPT under high-frequency sinusoidal voltage and validated with experimental results. Our findings analysed the characteristics of surface discharge under sinusoidal voltage and discussed factors that influence the surface discharge of PI insulation.
