This paper is focused application of chosen thermal non-contact and contact methods for quality diagnostics of the transformer windings. In the first part of the paper it examines basic principles and application of non-contact temperature measurement on power transformers by thermovision. The second part is focused on analysis of thermal processes in distribution transformer. In the finally, it is examined experimental measurement on laboratory transformer with task to detect mechanical strength and subsequently short-circuit resistance of its winding. By means of the experimental measurements and following analysis it was showed the practical thermovision and contact thermal measurement by optical detectors for diagnostics of power oil transformers in field mechanical strength of winding material.

Thermal diagnostic systems and their application for analysis of transformer winding
