FIELD: electric power industry.
SUBSTANCE: invention relates to the electric power industry and can be used to determine the location of damage on power transmission lines or networks, in particular, for remote determination of the coordinates of the place of occurrence of a corona discharge on a high-voltage power line. Two radiometers are placed at a stationary observation post. The optical system of the first narrow-field radiometer forms a field of view, one that's narrow in the vertical direction and wider in the horizontal direction. The optical system of the additional radiometer forms another field of view, narrow in the horizontal direction and extended one in the vertical direction. Then the geographical coordinates of the location of the stationary post with radiometers and of the supports of the high-voltage power line section are to be determined and fixed. Moving the field of view of the additional radiometer along a rectilinear trajectory within all the wires on the section of the high-voltage power transmission line to be monitored, the angular position of its optical axis is fixed, on which the radiometer registers a signal indicating the presence of radiation. The geographic coordinates of the projection onto the horizontal plane of the radiation source are calculated. The field of view of the first radiometer is moved within the angular size in the vertical plane of the field of view of the additional radiometer. The angular position of the optical axis of the first radiometer is recorded, on which it registers a signal indicating the presence of radiation. The height of the radiation source is calculated. The geographic coordinates and the relative height of the radiation source are displayed. The operations are repeated sequentially until the end of the section of the high-voltage power transmission line to be controlled.
EFFECT: increased efficiency in determining the coordinates of the place of occurrence of corona discharge on an extended section of a high-voltage power transmission line.
