Dielectric Property Measurement of Insulating Paper by the Gap Variation Method

A brief convenient method of examining the characteristics of the dielectric properties of paper specimens, and the experimental results using the gap variation method are · presented. The dielectric property measurement of paper specimens as thin as 30 microns is possible. Paper specimens of such a size can be measured one sheet at a time and need not be stacked to be measured, as is the case with conventional methods. The dielectric properties of a specimen that is kept air tight in a thinfilm polymer pouch can be measured with no effects from the ambient atmosphere.
