摘要: This study reports experimental studies of creepage discharges on the pressboard (PB) surface in esters under ac divergent electric field. With help commercial partial detector, wideband current measurement and high-speed image recorder, differences discharge patterns between open gap PB were studied as well mineral oil. The results show that presence tends to promote discharges, especially negative enables more occur at smaller phase angles. It is believed promotion effect caused by charges bubble residences; because intense higher viscosity esters, this significant than
