Transformer Oil Purification

Processed using a device called Oil Purification Plant. With reduces contamination and
physical, eliminates in the form of particle contamination, water content and gas.
Transformer oil purification process in general through 3 stages, namely filtration,
de-humidification (reducing water content) and de-gasification (reducing gas levels   dissolved).

Transformer Oil Reclamation

If the condition of the transformer oil is found the condition was so bad, 
that it appeared the risk of transformer oil capability will reduced ability 
to perform functions mainly. In this state oil The transformer needs 
to undergo a process regenerate to return it to
Near new condition according to IEC standards 60422 or IEEE C57.106-1991.
