要約(英語): 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.
