The expounded method of impulsive expose of defect of power transformer at excitation in him of damped oscillations by the periodic impulses of constant voltage. On the size of change of parameters of these vibrations at exploitation of transformer it is possible to estimate the origin of defects by the periodic diagnosticating and comparison of defectograms with normograms and to forecast development of defects and define possibility of after exploitation of transformer without the necessity of permanent or capital repair.
