⚡️ Transformer oil degassing. We'll tell you how it was 🔧

Last week, our #EDS_Substation team worked on an important stage of preparation of TMN 16000 transformer at one of the construction sites - transformer oil degassing.

To perform the work, we used the UVM 10-10 U1 unit.
It is designed for degassing, dehydrating, filtering, heating and nitriding transformer oil, which is poured into power transformers and other oil-filled devices with a voltage of up to 1150 kV inclusive.

Thus, it allows:
✅ remove gases that reduce the dielectric properties of the oil
remove moisture that can cause corrosion or damage to the insulation
✅ clean the oil from mechanical impurities;
✅ heat the oil to improve its properties;
✅ perform nitriding of transformer oil.

In addition, it can be used for:
🔸 heating the active part of transformers;
🔸 removal of aging products by spraying (“oil-spray”);
heating of oil-filled devices with hot oil.

🔍 Why is it necessary?
Degassing of transformer oil is a mandatory step to ensure reliable operation of a transformer, especially a powerful one like TMN 16000. Removal of gases and moisture ensures stable insulation, reduces the risk of damage and extends the service life of the equipment.

🛡 The transformer design uses a flexible-shell oil conservator, which additionally protects the oil from oxidation and moisture under the influence of air.

👌 The result: the transformer is ready for operation, and the facility's energy infrastructure is one step closer to completion!
