MARTINS, Maria Augusta G.. Regeneração de óleos isolantes usados.: Solução ou problema?. C.Tecn. Mat. [online]. 2007, vol.19, n.3-4, pp.88-94. ISSN 0870-8312.

The disposal of great quantities of degraded insulating oils has become more and more an environmental concern. This situation played an important role in the development of insulating oil reclamation methods, whose application intends to minimize this problem. This paper reviews the most common reclamation methods used for insulating oils, the basic process mechanism, and the main reclamation technologies. Furthermore, the advantages, and drawbacks of the “on-line reclamation” of insulating oil contained in power transformers (oil reclamation treatment while the transformer is energised at rated load) are also discussed here.

Keywords : Reclamation; On-line reclamation; Transformer; Insulating oil; Treatment.
