Oil regeneration and manhole entry

During operation of the transformers, the regeneration plant converts the contaminated insulating oil of the transformers into clean new oil.

The insulating oil is one of the biggest weak points of the transformer, it has to be incorporated into a maintenance concept. Since the service life of insulating oils does not correspond to the service life of transformers, various measuring techniques are used to determine the condition of the oil so that measures can be taken in good time.

Clean insulating oil reliably extends the life expectancy of transformers by many more years. With conventional oil treatment or oil exchange, this is only successful for a short period of time and is very cost-intensive.

Recommended when the following parameters are exceeded:
Water content, breakdown voltage, turbidity, particle content, colour number, interfacial tension, neutralisation number, dielectric loss factor, sludge, corrosive sulphur.

  • Oil condition can be restored to IEC 60296 and IEC 60422 level
  • Extension of the remaining service life.

Crash protection on power transformers

For the purpose of maintenance, revision and repair, transformers have to be planned or unexpectedly climbed. In contrast to fixed baffles, which have to be dismantled for the operation of the plant, fixed stop structures are available at any time.

According to the relevant regulations of the professional associations, personnel must be secured against falling.
