  • Publication number: 20190304657
    Abstract: An electric transformer is provided. The electric transformer includes an electric transformer main body and a heat radiating portion including a pipe configured to introduce an insulating oil into the electric transformer main body so as to absorb heat generated from the electric transformer main body, and the pipe is provided with a fixing member to which a sensing member is coupled such that the sensing member is exposed to the inside of the pipe so as to detect a dissolved gas in the insulating oil.

  • Patent number: 10191114
    Abstract: The present invention relates to a system for analysis of partial discharge defects of a gas insulated switchgear capable of allowing a user to precisely analyze a defect of a gas insulated switchgear due to a partial discharge, by providing both partial discharge signal information on a partial discharge signal sensed by a detecting sensor, and detection signal information on a detection signal sensed by one or more neighboring sensors adjacent to the detecting sensor, to a monitor.
