  • Transformer Oil Hydrotreating case study

    Hydrogenation of waste transformer oil (electrical insulating oils) can produce an oil product that is far better in quality and yield in comparison with fixed bed clay adsorption or reaction with sodium metal. This is proven at Sequoia- client’s facility in Midwestern USA. The 5 million gallon/year throughput naphthenic oil hydrotreater produces oil free of PCBs (polychlorobiphenyls ...

  • Transformer oil quality control

    It is impossible to ensure reliability and longevity of energy systems without controlling the quality of transformer oil. Recent experience shows that approximately 30% of transformer oil, filled in power transformers, has deteriorated to the point when it becomes a risk factor. This is caused both to natural degradation of oil in operation due to thermal oxidation aging, and contamination with ...

  • On-site regeneration of transformer oil

    Regeneration of transformer oil at the transformer’s location is an important preventive measure of transformer servicing.   Transformer life time is, in essence, the life time of its insulation system. The most widely used insulation is liquid insulation (transformer oils) and solid insulation (paper, i.e. cellulose insulation). The oil provides for at ...

  • Time to replace your transformer?

    Modern oil transformers are not the strongest part of the connection between energy producers and consumers. Transformers have no moving or friction parts, their efficiency of voltage transformation is close to 99%, therefore their life time extends, or rather can be extended well over several decades. Extending transformer lifetime is the one and only most important strategy ...

  • Why regenerate transformer oil?

    Article contain the information about the most important definition in transformer oil treatment. Its include terms such as transformer oil regeneration, insulation oil regeneration, purification of oils, degassing of oil, oil treatment, filtration by Fuller's earth, desludging, etc.  Regenerating the oil or other insulating medium in a transformer is probably one of the few environmentally ...

  • Series KPH transformer oil regeneration device

    Application: Series KPH transformer oil regeneration device use of a special active clay for purifying and regenerating the unqualified transformer oil, switch oil, mutual inductor, it also can be used as absorption unit for treating low viscosity lube oils. Series KPH can remove acid, free carbon, oxides, pigment and particles, it dose not affect insulating oil ingredients and anti-oxidation. ...

  • Modelling oil degradation in electric transformer oil under typical loads

    In testing transformer oils for durability, it is desirable to use typical transformer operating conditions with appropriate allowances for factor of safety against temperature and voltage. The kinetics of degradation of used type II transformer oil with original flash point of 148?C, pour point of 51?C, and water content of 4 ppm was investigated. Assuming that the oil temperature in models Pr01 ...
