METHOD OF MONITORING TECHNICAL CONDITION OF ELECTRIC POWER FACILITIES Russian patent published in 2017 - IPC G01R31/00 

FIELD: electricity.

SUBSTANCE: invention relates to the diagnosis of electric power facilities. Essence: everything is measured in equivalent conditions for a controlled and a one-type reference objects, the energy spectra of electromagnetic radiation of horizontal polarization of all the objects' equipment on joint action frequencies of white noise and quasi-harmonic oscillations with resonance frequencies of good-quality oscillatory circuit equipment of these facilities. It is allocated and fixed in the measured spectra of the intensity of white noises. The complete deficiency of the controlled object is determined by comparing the intensities of fixed white noises in the energy spectra of the horizontally polarized radiation for the controlled and the reference objects. The defectiveness of the object is defined as a weak, moderate, severe or dangerous, if the intensity of white noises in the energy spectra of the horizontally polarized radiation for the controlled object exceeds this figure in the reference object by an amount respectively to 15, 15 to 30, 30 to 45 and more than 45 dB . The energy spectra of electromagnetic radiation of horizontal polarization was measured by a standard industrial equipment. The measuring devices are placed in the middle of the controlled or reference object directly above or below the high-voltage input (BB) transmission line near the BB OPY. The main recommended frequency measurement range is in the low part of the scope of the white noise at the frequencies f = 3-300 MHz or alternate embodiment of frequency f = 3-3000 MHz.

EFFECT: invention provides simplification, improving the reliability and efficiency of diagnosing of electric power facilities.
