Electric and Dielectric Properties of Epoxy Resin as Insulating Material for High Voltage Systems - (PPT)

摘要

Thermal shock stresses lead for all investigated cast resins to a lasting deterioration of the partial discharge inception voltage. The change of the inception voltage over thermal stress cycles is mainly influenced by the resin system. A decline of the partial discharge inception voltage is often combined with a rise of the partial discharge rate and the average charge value, leading to an increasing energy.
