FIELD: electricity.
SUBSTANCE: method of diagnostics and control of short circuit of active steel sheets in cores of electric machines by means of scanning according to the invention is carried out by laser scanning in the range of long waves of 300-1500 nm, monitoring of condition of electric steel sheets is carried out with the help of an analyser of oscillations of intensity of laser radiation scattered in the core, the diagnostic sign is change in amplitude of oscillations of intensity of radiation scattered in the diagnosed section of the core, monitoring of damage of electric steel sheets condition is carried out by measurement of amplitude of oscillations of intensity of radiation scattered in the core, and diagnostics of extent of damage of electric steel sheets condition is carried out by means of comparative analysis of the result of produced error of measurement of amplitude of oscillations of intensity of radiation scattered in the good core, and amplitudes of oscillations of radiation intensity scattered in the tested core.
EFFECT: higher validity of diagnostics and monitoring of sheets of active steel in a core of electric machines during preventive tests and repair.
