摘要：
The paper presents measurements results of transformer oil percolation through electrotechnical pressboard. On the basis of the measurements, the oil penetration times by largest capillary in the pressboard, were determined. Reduced density areas have been found in pressboard, which may potentially cause a local decrease in dielectric strength of paper and oil insulation.
