N2 Gas Equipments

N2 gas equipment (or N2 gas sealed equipment) is an apparatus to insulation oil from oxidization by means of isolating insulationoil from atmosphere.
To attain this purpose, N2 gas is filled above insulation oil level inside the tranformer by using the N2 gas equipment. The variation of pressure level or vacuum level inside the transformer, caused by ambient temperature and/ or the load change of transformer, can be automatically controlled by the equipment.

In addition to above, the equipment is generally used as an apparatus to supply N2 gas inside the transformer tank during its transportation instead of insulation oil.
