Mobile Vapour Phase Equipment

To extend the life time of high voltage power transformers, it is necessary to extract the water moisture from the paper insulation. This new development allows to dry high voltage transformers in the field with the advanced vapour phase drying technology. Until now, this technology has only been used for the drying of active parts during the production process of new power transformers and repair transformers.

The repair transformer is dried in its own housing. Residual moistures similar to new transformers can be reached. Residues of cracked transformer oil can be removed from the surface of the insulation material. The cost-intensive transport of the transformer to a repair workshop is no longer necessary. Life time of repair transformers can be extended.

The mobile compact vapour phase drying equipment with the flash evaporation system fulfils all demands of an ideal drying process of transformers. Drying times and residual moisture contents of insulation materials are similar to the common vapour phase drying technology in transformer production factories. The residuals of used transformer oil can be removed very efficiently. Therefore the drying of transformers in their own housing in the field or in repair work shops can be done successfully with the new system.

In the meantime, this technology is requested for the drying of new ultra high voltage power transformers, which have to be assembled in the field substituting the hot air drying technology. On the other hand this technology opens the market for the cost efficient drying for small power transformers as well as distribution power transformers with vapour phase drying technology.
