要約(日本語): We have been investigating dielectric characteristics of 3D-printed epoxy resin for applying to power systems. Previous studies have shown that lightning impulse breakdown characteristics of 3D-printed epoxy resin may have bigger polarity effect than that of casted epoxy resin. However, because 3D-printed epoxy resin has larger surface roughness than casted epoxy resin in these studies, it is possible that surface condition of epoxy resin, such as surface roughness, may cause this effect. The purpose of this paper is to reveal the influence of surface roughness for polarity effect by investigating lightning impulse breakdown characteristics of 3D-printed epoxy resin.
