Abstract :
The authors use simplified model schemes for studying the static and dynamic processes of ion movement and charge carrier deposition in the board oil system. An approximate sample calculation has been made. The benefits of a novel Transformerboard material with a lower resistivity are shown. Computer field plots of the voltage distribution at AC and DC in a typical composed transformer insulation are presented
