- treats transformer on-line
- treats any transformer oil.
Scope of application.
Many of industrial electric systems contain dielectric oils. Extending the lifetime of the equipment and the oil it contains requires the dielectrics to be prepared and periodically treated. Thermal vacuum drying and degassing of dielectrics is a method of such treatment. In combination with filtration this technique allows to extend the life time of oil filled equipment significantly.
Long term use of oils causes the oils to degrade thermally and chemically. The products of such degradation are chemical elements adversely affecting the oil’s dielectric properties as well as operation of electric equipment. This problem is solved by periodic oil regeneration.
The plant is used during installation, maintenance and operation of oil-filled high voltage equipment (power transformers, high-voltage switchgear, etc.).
The plant is designed for processing of electric insulation oils and servicing of transformers.
The process of dielectric oil treatment includes the following:
Removal of gases solved in the oil.
Removal of free and dissolved water.
Removal of solid particles.
Removal of oil decomposition products.
Transformer servicing includes:
Transformer evacuation.
Heating of the transformer and the active part of the windings with hot oil.
Removal of sediment from the windings.
