抄録

For the purpose of supporting the understanding of partial discharge (PD) phenomena for student education in electrical engineering, an introduction of experimental proposal for practical training which includes experiment and theoretical calculation is taken into consideration. In succession of the technical education for diagnosis of insulation degradation, the knowledge about PD carried out an important role in the background of this consideration. The experimental sample which is laminating an insulated board with a cylindrical shape cavity between the common glass-reinforced epoxy laminate boards, which mostly used in printed circuit boards, was made for the evaluation of the internal PD phenomenon. In addition, the medium-layer board with the cavity was evaluated also to the case where it was considered as a PTFE board and a CFRP board. The content of this experiment is intended to make it understand the intensity of internal PD generated by impression of AC high voltage. The amount q of charges (the apparent amount of PD charges) in the cavity was observed first, and the amount qmax of the maximum charges was evaluated below as compared with a simple calculation model.
