A charging potential of a floating electrode modeled on vacuum interrupter was measured under unipolar AC voltage application using a surface potential meter. As a result, when a lower voltage was applied to the samples, only an induced potential depending on the electrostatic capacities of the sample and surrounding objects around the sample was measured from the floating electrode. However, in the case of high voltage application, not only induced voltage but also a positive charging potential was observed from the floating electrode which was enough to change the potential of the floating electrode. This is due to the field electron emission from the floating electrode itself.

交流电压施加下基于真空灭弧室电弧罩的浮置电极的充电电势测量

使用表面电势计在单极交流电压施加下测量以真空灭弧室为模型的浮置电极的充电电势。结果,当向样品施加较低的电压时,仅从浮动电极测量取决于样品的静电电容和样品周围的周围物体的感应电势。然而,在施加高电压的情况下,从浮动电极不仅观察到感应电压,而且观察到正充电电势,其足以改变浮动电极的电势。这是由于来自浮动电极本身的场电子发射。
