Prophylactic Diagnostics for Electrical Machines

The paper is focused on analyses of online diagnostics with analysis of induction motor, transformer and AC generator by means of thermovision measurement. In the 1-st part of article is performed theoretical analysis of thermovision measurement on the base infrared thermal radiation. In the 2-nd part of article is performed experimental diagnostics and analysis by thermovision camera on induction motor, high-voltage transformer and AC generator. In the end are performed conclusions according to measured values by the means of thermovision analysis.
