Abstract: The present disclosure relates to a method and apparatus for measuring corona discharge of power facilities by a UV sensor with an optical lens. The apparatus includes a UV sensor array receiving UV rays from an analyzing target of a power facility at a location separated a predetermined distance from the target, an optical lens unit focusing the UV rays to the UV sensor array, a signal detector detecting the UV rays in the form of a pulse voltage waveform signal, a UV image processor processing the detected pulse voltage waveform signal into a UV image, a real image measurement unit photographing a real image of the analyzing target, a real image processor displaying a photographed real image; a matching unit combining the photographed real image with the UV image, and an image/data output unit detecting a location of corona discharge based on the combined UV image and real image.

Abstract: Disclosed herein is a method and apparatus for measuring partial discharge using a UV sensor array. The apparatus includes a UV sensor array including plural sensors detecting UV rays from an analyzing target of a power facility at a location separated a predetermined distance from the target and converting the UV rays into discharge current, an image measurement unit measuring the distance between the sensor array and the target and supplying an actual image of the target, a UV intensity detection unit measuring intensity of the discharge current converted from the UV rays detected by the sensor array, and a UV location detection unit analyzing and outputting a UV emitting location obtained by matching the discharge current intensity measured by the UV intensity detection unit to combined data of the actual image of the target supplied from the image measurement unit and sensor locations of the sensor array.
