APPARATUS FOR DETECTING INTERNAL FAULT OF TRANSFORMER

摘要

The present invention relates to an apparatus for detecting an internal defect in a transformer, which comprises an electrode for detecting an electric defect and a sensor for detecting an internal gas, and detecting the internal defect generated in the transformer by inserting the sensor into the transformer. A transformer internal defect detection apparatus according to the present invention comprises: a metal member having a predetermined length; A plurality of electrodes provided around the metal member for detecting an electrical signal generated by internal defects of the transformer; An insulating member formed to include the metal member and the plurality of electrodes; And a gas sensor installed at an end of the metal member for detecting a gas inside the transformer.
