Transformer oil purification by adsorbents and the ceramic membrane

Environmentally friendly regeneration of used energy oils

“…Bentonite (alkaline) from the Navbakhor deposit, which was discovered in 1998, was used as an adsorbent for the regeneration of transformer and turbine oils. The material composition of these bentonite clays has been studied and reported in [4,5] with the involvement of complex laboratory methods (chemical, thermal, ESDO electron microscopic and X-ray diffraction analyses).…”

Investigation of factors influencing the operational characteristics of traction transformers

“…Its malfunction or downtime leads to a lack of power supply to the rolling stock, which, in turn, leads to a downtime of the rolling stock and, as a result, to many other problems (late arrival of passengers and cargo at the destination, violation of traffic schedules, etc. ).The uninterrupted and trouble-free operation of electric trains depends on the condition of the traction transformers [1,5,6]. Analysis of literature sources shows that [7][8][9][10][11][12][13][14][15][16] during the operation of transformers, malfunctions can be observed in the form of failure of the magnetic circuit, insulation failure, faults at the output of the transformer, oil leakage, cracks inside the transformer, excess of the permissible oil temperature, violations of oil circulation, loss of dielectric properties of oil, cracks in the rods, transformer operation with noise.…”
