DEVICE FOR DETECTION AND MEASUREMENT OF ELECTRIC DISCHARGE OF HIGH-VOLTAGE EQUIPMENT Russian patent published in 2020 - IPC G01R31/08 G01R31/50 G01R1/07 

FIELD: measurement.

SUBSTANCE: invention is related to electric measuring equipment and concerns device for detection and measurement of electric discharge of high-voltage equipment. Device includes observation and measuring branches, range finder and information processing and display unit. Receiving optical system is a mirror lens which is common for the observing and measuring branches. After the mirror lens, there is a diffraction grating made with the possibility of transmitting in the zero order of diffraction of the radiation flux in the visible and infrared spectral ranges to the observation branch, and in working order of diffraction - radiation flux in ultraviolet range of spectrum in measuring branch. Measuring branch is additionally equipped with a spectral slot installed along the beam path in the working order of diffraction of the diffraction grating between the band-pass optical filter and the photodetector. Observing branch along the beam path in the zeroth order of the diffraction grating is additionally equipped with a spectrum splitter configured to divide the radiation flux into the visible and infrared spectral ranges.

EFFECT: technical result consists in improvement of probability of detection and accuracy of measurement of electric discharge at any time of day.
