Title: APPARATUS FOR DETECTING INTERNAL DEFECT IN TRANSFORMER
Abstract:
The present invention relates to an apparatus for detecting internal defects in a transformer, the apparatus detecting internal defects that arise in the interior by integrating an electrode for electrically detecting defects and a sensor for detecting internal gas into a single body and inserting same into the interior. The apparatus for detecting internal defects in a transformer according to the present invention comprises: a metal member of a set length; a plurality of electrodes, disposed around the metal member, for detecting electrical signals generated due to internal defects of the transformer; an insulating member formed so as to contain the metal member and plurality of electrodes; and a gas sensor, installed at the end of the metal member, for detecting gas inside the transformer.
