Realtime Vacuum TransformerOil Regeneration Purifier with Remote Monitoring

of light oil fractions enables the liquid piston principle simultaneously. In the first stage (evacuation), the sinking oil level acts as a piston and creates the vacuum necessary to separate gases and vapors from the oil. In the second stage (compression), the liberated gas mixture is gradually compressed by the rising oil level. The condensation of oil vapors takes place and the light fractions get mixed back in the oil. Only non-condensable substances are then expelled from the drier into surroundings.

The basic rule for any treatment of the oil inventory is to remove only the undesired substances from the oil. The soft removal of the diluted water from the oil is easily achieved (without a high vacuum and high temperature, which potentially deteriorate the oil), by freezing up the water vapor under low vacuum and by reaching oil temperature rates at only about 60 degrees, because the water removal process is simultaneously intensified by a so-called bubble bed procedure. A continuous degassing of the oil without the undesired removal

How it works?

-new transformer oil causes down time to leave out, clean and fill up and so on and life extension technology causes no downtime

-new transformer oil must bee monitored also, to guarantee up-time

-new transformer oil is no guaranty for secured cellulose (mostly water is in cellulose)

But - what is better?

On the other side are minimum 25.000 liter of new bought transformer-oil.

This life extension solutions cost approximately 70.000 Euro plus service cost plus other cost like transport etc.

-transformers with 80 KVA have approximately 15.000 liter oil

-transformers with 5 kVA have approximately 1.200 1.300 liter oil

-transformer-Oil costs 2,50 and 3,00 Euro per liter

cost-effectiveness calculation:

Wet power-transformers between 5kVA and 900 MVA

What transformers can be treated with this technologies?

 

- the principle is to abstract water from the transformers oil to raise breakdown voltage and for this extend lifetime of cellulose - the main problem why transformers break down is if Cellulose is dissolving in case of bad transformer-oil quality.

Solution:

- insurance companies don?t pay a damage, if a company could?t not verify, that every security and care for the transformer was done. If they find any carelessness they will not pay the damage!

- they have accelerated rising prises - if they break down it causes downtime of production (worst case for every company or power station) - they have bad availability all over the world (waiting time on new transformers up to 3 years) - they have to work 24h and 7 days per week (no rest allowed)
