Abstract
A partial discharge detecting method using ultraviolet imagery under pulse voltage condition is discussed. The method samples video data at a partial discharge area of a target electric system by an ultraviolet imager, obtains an ultraviolet image by extracting video frames from the video data, obtains a discharge intensity data P based on a sum number of pixels with a brightness value higher than a brightness threshold in the ultraviolet image; and obtains a quantization result Q of the partial discharge of the target electric system based on the discharge intensity data P and discharge characteristic parameters.
