要約(英語): Insulating performance of DC high voltage instruments are affected due to contamination of floating particles with its instruments or systems. Especially, the effect of charging floating particles are serious because insulation performance of high voltage instruments decreased. This is because neighborhood floating particle which is charged enhanced the electric field. The charging phenomenon of floating particle have numerous possible causes. For example, contact charging, ion stream which are caused by partial discharge and natural radiation. In this work, we researched the laser charging effect of a metallic particle, which are made of steel and φ = 2.0 mm in diameter, in DC high voltage quasi-uniform field gap at atmospheric pressure. As a result, the polarity and the charge amount of a metallic particle were controlled by YAG-laser. In addition, breakdown voltage and corona discharge voltage were measured and compared to simulation value in this configuration.
