On Line Transfomer Oil Purification

Our post oil treatment of regenerated transformer. We would like to inform you that, CEE DEE Vacuum with its advance method has done “On Load Transformer Drying, Desludging, Oil Regeneration process” last year. The oil values (Performance) achieved was excellent & was as good as New Oil (IS 335).

To retain, these qualities of oil & transformer drying performance for long duration of time, we strongly recommend end user to go for “ON – LOAD” Transformer oil purification & Drying process. This “On – Load” drying/purification process will maintain oil quality as well as dryness of insulation inside Transformer.

In case some of the oil parameters crosses its limits of acceptance, then its should be Regenerated again considering the valves disturb. Hence to maintain oil in good condition, please process the transformer oil purification “on-line – on-load”
