new current transformer leak detection

The nonlinear characteristics of magnetization of a current transformer (CT) can cause waveform distortion in the secondary current, which may result in malfunction of protective relays. This phenomenon is known as CT saturation. The accurate saturation detection, with the use of digital-signal-processing techniques applied to secondary current, plays an important function in solving the ...

  • Vaisala Identifies New Air Leak Detection Method for

    Vaisala Identifies New Air Leak Detection Method for Transformers. An oxygen sensor cannot detect an air leak, if there is a reaction in a transformer that consumes oxygen. Even if all oxygen has been consumed, TGP value will still give a reliable indication of a leak because the nitrogen value will both dominate and increase over timeEstimated Reading Time: 2 mins

    In this paper, the improved morphological gradient algorithm and the morphological decomposition algorithm are used to detect the saturated sections of a secondary current, and the detection results are combined by the AND logic so as to provide a more accurate and reliable detection result. The proposed method is implemented in a system on chip, whose core is a field-programmable gate array

  • A new way to detect leaks in pipes | MIT News

    2021-3-7Caption: A test version of the new detection system is seen in the lab, where it underwent tests inside glass tubes to allow its operation to be observed. The propulsion module, at right, is fitted with electric wheels and motors to move the device through the pipe. The leak sensor, at left, is a drum-shaped membrane that can sense changes in pressure caused by the presence of a leak.
