FIELD: electricity.
SUBSTANCE: invention relates to a lightning discharge indicator installed in a high voltage power transmission line bushing, which comprises an insulating body, electrical fittings for fixation of the bushing and/or a retained wire, a discharger and at least one element of voltage supply, installed as capable of supplying electric voltage from electrical fittings to a discharger to form a discharge gap with a discharger. The indicator comprises a solid layer of a dielectric arranged on the voltage supply element so that the minimum distance from the discharger to the edge of the dielectric layer is more than the minimum distance from the discharger to the surface of the dielectric layer. Besides, the indicator comprises an indicator element arranged with usage of a dielectric and with adjacency as capable of disconnection on the dielectric layer on the line on the dielectric layer surface, which connects the point on the dielectric layer surface, having minimum distance to the discharger, and the point at the edge of the dielectric layer, which is least distant from the specified point on the surface of the dielectric layer, having minimum distance to the discharger.
EFFECT: simplified design, higher safety and convenience in operation of an indicator, providing for the possibility of visual detection of lightning discharge.
