We had investigated the breakdowns in Tape Lapped Joints for power cables.
We thought that the several gaps generated accidentally and continuously in the overlap of the insulating tapes and became the big gap. And we assumed that the electric field leading to breakdown generated in this gap.
Therefore we used JMAG for electric field analysis.
As a result of the analysis, we were able to confirm that the electric field which generated in the gap did not lead to breakdown. In Addition, we were able to focus on the true cause.
