Portable optoelectronic device for detecting the corona discharges in high-voltage power lines

In using the electric power lines (EPL), a major problem is the location of initiating the corona discharges causing high power losses and a failure of different EPL elements. A portable optoelectronic device for detecting the EPL faults by a method of remote measuring of their UV radiation is developed. The device detects a point corona discharge from a distance of 150 m. The detector is a monoblock and its service is provided by an operator.
