This article deals with problems of prophylactic measurement and condition of electrical machines using thermovision diagnostics. It examines the basic principles and uses non-contact temperature measurement. The knowledge of the problems of diagnostic of electrical machines in service without disassembly enables us to use more efficient thermo-diagnostic methods and to localize the failures that determine the quality of electrical wiring and equipment. The degradation of insulation materials due to temperature puts increased demands on precise knowledge of the thermal conditions in a given electrical machine. In the article are presented thermovision experimental measurements on asynchronous motor, transfer power transformer 242 kV and high-voltage generator 220 MW. Except for analysis of failures of listed power devices, thermovision technology was also used for checking of electric machines and devices for detecting of the temperature on the pick-up systems and excitation systems of generators, power parts of electric machines, detecting of the temperature differences on the semiconductor valves in individual parallel branches of equipment.
