Discharge Characteristics from a Water-Penpoint-to - Insulator-Paper-Covered-Plate Airgap

수성(水性)펜침(針) 대(對) 절연지부착평판간(絶緣紙附着平板間)의 방전특성(放電特性)

Some interesting corona characteristics of a airgap of penpoint-to-plate with a tracing insulator paper has been investigated in a temperature and humidity controlled metal chamber. It is found that the positive and the negative carriers in the plasma region could be understood from the waterdrop traces on the paper, which indicate the bombardment by the one of electron or positive gas particle from the plasma region of near the point. It is also found that a corona discharge could be used as a means of a humidifying, since the discharge makes dispersion of watersprays from the penpoint. And the negative corona was more effective for waterspray dispersion than the positive ones.
