Abstract

In manufacturing high-temperature superconductor (HTS) devices, outgoing control of their quality must be carried out. Conventionally, for coils made of HTS, electrical tests are carried out to determine the critical current. In case of an unsatisfactory result, the reason why the critical current is below its expected value should be determined. The HTS tape coil manufacturing quality should be checked on the basis of non-destructive test methods. The article proposes an HTS coil examination technology, according to which the actual locations of the tape and gaps between the coil turns and rows are determined with subsequently analyzing the obtained values. To this end, the samples were scanned using the computed tomography method on the Nordson Dage XD7600NT X-ray machine with the μCT module, and the data obtained were processed using the VolumeGraphics VGStudio 2.2 visualization software. The proposed technology can be used as part of a predictive analysis of the state of the HTS coils of electrical machine windings.
