  • Transformer Monitoring - Online Dissolved Gas Analysers

    A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of Moisture in Oil (H 2 O) and the key gases Hydrogen (H 2), Carbon Monoxide (CO), Acetylene (C 2 H 2) and Ethylene (C 2 H 4) dissolved in transformer oil. This extra data from the HYDROCAL 1005 reduces the amount of maintenance time because the probable cause of any faults will have been established before action takes place.

  • Six Common Data Issues in Transformer DGA - Delta-X Research

    Gas concentrations vary greatly from sample to sample. Poor repeatability of gas concentration measurements can mask small changes indicating a problem in its early stages and make it very difficult to identify and assess any fault that is detected. One oil sample’s gas concentrations are very different from the other samples. A human error may have occurred such as: mislabeling a sample from a different oil compartment or a different transformer; interchanging gas values, such as N2 and O2; or duplicating, reversing, or dropping digits in a number. Contradictory information. If hydrogen concentration decreases sharply while other gases remain roughly the same as before or even increase, the oil sample might have been exposed to air or a gas bubble might have been expelled from the sample syringe. Hydrogen concentration is extremely low in all samples. Hydrogen gas escapes quickly if there is any chance, and a transformer will gradually lose other gases if it “breathes” by design or there is a leak such as a ruptured conservator diaphragm.
