Problem #4: Dissolved gas and/or decay products
Nature of Problem:
During its lifetime, the transformer generates decomposition gases, essentially from the organic insulation, under the influence of various stresses, both normal and abnormal, which could lead to failure if ignored.
The UVM unit is designed for degassing, drying, removal of solid particles and heating of transformer oil used in power transformers up to 1150V.
The unit can process mineral oils with the following properties:
Dynamic viscosity, mm2/sec, at 50 °С 2…12;
Density at 20°С, kg/m3 800…950;
Moisture content, ppm, max 100;
Purity class ISO 4406, at least -/19/16
The UVM unit is available in different design configurations, Zeolite Filtration Section CP-260 is available as an option.
Processing rate 4 – m3/hour
Capacity 8 m3/hour
Capacity from 1.5 to 4.0 m3/hour
|The UVM unit is designed for:
· Vacuumizing transformers;
· Removal of solid particulate matter;
· Removal of water;
· Removal of gases
||The unit is placed on a tandem axle trailer that is street legal and ready to be towed to any remote location
|| This unit is designed to significantly reduce acid levels in used insulating oil
