Water in the active parts of the transformer can have adverse effect on its lifetime. The indicative lifetime of insulation at 80 C and 1% moisture is around 40 years whereas with 3% moisture it is 10 Years. Furthermore the reliability and overload capacity of the transformer are also affected when moisture is present. Transformers are more susceptible to mechanical stresses during short circuits when moisture is present. Vacuum Drying uses hot air circulation to remove moisture from the insulation
Vacuum Drying is one of the most common processes which reduces the moisture content from the insulation. Using hot air circulation and vacuum, rapid drying can be achieved without damaging the product. SAVAS has installed a large number of vacuum drying plants as per customer requirements. Our experience enables us to understand your requirement and provide standardized components and solutions tending to your needs.
