要約(英語): To understand the electrical treeing properties at an interface, treeing breakdown tests are performed using a 1/2 needle polished to half the original thickness. The treeing properties of multilayer samples, which have interfaces similar to Epoxy (EP)/EP-1/2n and Glass/EP-1/2n, are measured. The average tree inception voltage of the EP/EP-1/2n sample is higher than that of the Glass/EP-1/2n sample. The magnitude relationship of the bonding strengths between the EP/EP-1/2n and Glass/EP-1/2n samples is the same as that of the tree inception voltage. The insulation lifetime of the EP/EP-1/2n sample is also higher than that of the Glass/EP-1/2n sample. These results suggest that the interface becomes the weak point for electrical insulation, and the weak bonding of the interface may lower the treeing properties.
