Abstract
An electrical discharge measurement device for non-contact measurement of an electrical discharge having a discharge magnitude. The electrical discharge causes a corresponding emission of optical radiation. The electrical discharge measurement device has a light-collecting device for forming an image from the optical radiation from the electrical discharge, and an optical filter operatively coupled to the light-collecting device for preferentially selecting wavelengths at which the electrical discharge emits relatively intense optical radiation. An optical detector receives light from the light-collecting device and filtered by the optical filter for converting the filtered light to an electrical signal. An electronic signal-processing device provides, based on the electrical signal, a quantitative discharge measurement related to the magnitude of the electrical discharge.
