Effect of high frequency voltages on the trap distribution parameters of Nomex paper

Existing research considered that the trap parameters are a cause of concern to affect the degradation of turn-to-turn insulating material for high-frequency (HF) transformers. Especially, the influence of HF voltages on the trap parameters of Nomex paper is unclear. In this paper, an experiment system of trap parameter is constructed by using the method of isothermal surface potential.
