Cast resin transformer (CRTr) adopting the solid insulation method is superior in flame resistance as compared with the transformer adopting other insulation method. In addition, since it can be made compact and lightweight, it is used in various ind

In epoxy cast resin power apparatus, there exist unexpected insulation defects of voids and delamination. Existence of such defects can generate partial discharge (PD) with degradation of the epoxy, which eventually leads to electrical breakdown with

Summary It is crucial for proper insulation design of cast resin transformers to consider voids and delamination which might exist in cast molding because of several surface boundaries between resin and conductor. Such defects in the insulator lead t

Partial discharges of small-air-gap for the molded insulation system has been investigated in view of the Paschen curve. It was found that Vs (partial discharge inception voltage: PDIV) in a smaller Pd (pressure times gap distance) region than so-cal
