摘要

本工作演示了一种简单的方法来记录本禀局部放电(PD)活性的薄聚醚砜箔作为电应力的结果。PD电流的极性与施加电压的极性相反，或先前施加到高压电压电极的极性相反。局部放电也由暴露在来自激光源的紫外线下引起。这些初始放电相对于激励脉冲延迟20至50纳秒。放电是由于充满气体的空隙的存在。

Observations of intrinsic and UV-light initiated partial discharges (PD) in thin polyethersulfone (PES) foils

The present work demonstrates a simple method for recording intrinsic partial discharge (PD) activity in thin polyethersulfone foils as a result of electrical stress. The polarity of the PD current is opposite to that of the applied voltage, or that previously applied, to the HV voltage electrode. Partial discharges were also initiated by exposure to UV-light from a laser source. These initiated discharges are delayed for 20 to 50 ns in relation to the excitation pulse. The discharges are attributed to the presence of gas filled voids.
