    Sep 21, 2016 · Gaskets with poor seals are probably also leaking water and air into the transformer, in which case DGA samples should be obtained to check for high water and oxygen content inside the main tank. If oil levels are low and there is no evidence of external leaks, an internal leak could be present around the lower seal leading into the transformer tank.

  • Detection of Dissolved Carbon Monoxide in Transformer Oil

    AbstractIntroductionExperimental SetupResults and DiscussionConclusionAcknowledgmentsCarbon monoxide (CO) is one of the most important fault characteristic gases dissolved in power transformer oil. With the advantages of high sensitivity and accuracy, long-term stability, and short detection time, photoacoustic spectroscopy (PAS) has been proven to be one promising sensing technology for trace gas recognition. In this investigation, a tunable PAS experimental system based on a distributed-feedback (DFB) diode laser was proposed for recognizing dissolved CO in transformer oil. The molecular spectral line of CO gas detection was selected at 1.567 μm in the whole experiment. Relationships between the photoacoustic (PA) signal and gas pressure, temperature, laser power, and CO gas concentration were measured and discussed in detail, respectively. Finally, based on the least square regression theory, a novel quantitative identification method for CO gas detection with the PAS experimental system was proposed. And a comparative research about the gas detection performance...
