Partial discharge measuring apparatus using UV sensor array and method thereof

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.
