Film power capacitors are made out of polypropylene (PP) films co-wound with Al foil electrodes, impregnated with insulating oil. In a void, if any, or around the electrode edge, partial discharges (PDs) occur, leading to PP film deterioration and ev

2017 International Symposium on Electrical Insulating Materials (ISEIM).
The authors have been investigating the deterioration characteristics of polypropylene (PP) films due to partial discharge (PD) in a closed void as a basic study of longterm deterioration of power capacitors. We reported that (1) the number of PD pul

We have been trying to improve a quality of crystal, using the metastable solvent epitaxy (MSE) method, one of the solution methods. In MSE, a Frank-type fault is formed by conversion of a threading screw dislocation (TSD) in the substrate. To study
