develop leak detection for transformers

Meanwhile, a nitrogen leak can develop, and all the N 2 will be lost. This allows air with oxygen and moisture to enter and deteriorate the oil and insulation. Watch for increased oxygen and moisture in the DGA. An ultrasonic and sonic leak detection instrument (P-2000) is used for locating N 2 leaks. Soap bubbles also may be used.

  • Vaisala presents new air leak detection method for transformers

    Sep 23, 2020 · 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 time because it is neither formed nor consumed in the transformer. Additionally, TGP measurement can indicate if the nitrogen cylinder of a nitrogen blanketed transformer is empty – another task that oxygen measurement cannot
