TARGET.Thepurposeofthisworkistodevelopa non-contact laser control and measuring complex (LCMC) for vibration control of the level of pressing of windings and magnetic circuit of a power transformer. A laser vibrometer is used as a measuring element, the developed software in the LabVIEW graphical programming environment serves as a tool for processing vibration signals. The technical condition of the power transformer is analyzed by the amplitude spectra of the vibration of the tank of the transformer under study, formed using the fast Fourier transform algorithm in the LabVIEW software. METHODS.Thevibrationcontrolmethodmakesitpossibletocontrola power transformer during its operation under voltage, which makes it possible to move from a planned system of transformer repairs to a system for taking out for repair according to the current technical condition. RESULTS.ThedevelopedLCMCallowstocarryoutnon-contactmeasurementsofvibrationparametersofa power transformer under voltage and to establish the current level of pressing of windings and magnetic circuit. CONCLUSION.ThedevelopedLCMCwithsoftwareallowscontactlesscontrolofthetechnicalconditionofthemagneticcircuitandthewindingsofthe power transformer according to the amplitude-frequency characteristics of the vibration parameters, as well as the use of statistical methods for processing and analyzing signals received from the transformer.
