APPARATUS AND METHOD FOR DETECTING A CORONA

摘要

The present invention relates to an apparatus and method for detecting a corona. According to one aspect of the present invention, an apparatus for detecting a corona comprises: a sensing unit which senses corona discharges occurring in an electrical system; a signal-processing unit which converts the sensed corona discharges into a voltage signal; and a control unit which determines the level of abnormality of the electrical system using the converted direct current signal. The method and the apparatus of the present invention sense corona light and represent the level of corona discharges in numerical values to accurately enable the level of abnormality of the electrical system to be judged, and to enable an abnormality of the electrical system to be judged without particular expertise. The apparatus of the present invention can be conveniently carried by hand or mounted on a vehicle during the surveillance or inspection of the electrical system, and enables the inspection of a large-scale electrical system to be performed in a short amount of time, thus reducing operational restrictions.
