Sustainability, resource conservation and economic efficiency form an overarching triad in transformer management and for asset managers. How can this triad be ensured? What does transformer management involve? And what service does transformer oil provide in this context?
The supply of electrical energy only works with transformers. Their reliability influences the economic efficiency of the entire energy supply system.
That's why asset managers of transformers look at their plants very attentively from a technical and economic point of view and optimise them. They manage measures and budgets for maintenance and investment.
This also includes measures for environmental protection and resource conservation, which make the European Green Deal possible.
| By 2050, the EU member states want to become climate neutral. The initial goal is to reduce greenhouse gas emissions by at least 55% by 2030 compared to 1990 levels. To achieve this, all countries must be realigned in terms of energy. The EU's Fit for 55 package of measures proposes EU legislation and new initiatives that are in line with climate targets. Important here is the shift to renewable energy sources: By 2030, the share of renewable energy in the EU is to be raised to 40%. |
| The share of renewable energies can only grow with an increased amount of transformers The energy supply that comes with the energy transition poses special challenges for power grids. Electricity from decentralised, renewable energy sources is being integrated into the low-voltage grid. This must be transformed many times on the way from the power plant to the end consumer. |
In electrical networks, a large part of the costs are related to the maintenance of the equipment, including transformers:
Transformers must be functional at all times and unexpected repairs or operational failures need to be avoided. In addition, they are increasingly optimised in terms of their service life and aspects of sustainability are taken into account.
Technical managers or asset managers of transformers are responsible for
For this purpose, asset managers have the insulating oil of their transformers regularly analysed. They use the actual data collected through analyses and compare it with the planned data. This target/actual comparison is carried out regularly and used for corrections:
Managers of transformers are in particular managers of data
Documented data helps to set priorities. Which plant needs maintenance first? Which transformer needs which investment? What is the probability of failure of the respective equipment?
Laboratory analyses provide answers to these questions and inform about the condition of the insulating oil, determine the PCB content, the breakdown voltage, the water content or, for example, the paper thickness.
An insulating oil analysis provides information about the condition of the transformer oil, but also provides information about other assets.
Transformer oil is responsible for the efficiency of power transmission. It cools and insulates, protects against corrosion, lubricates the moving parts and has a cleaning effect. In addition, the condition of the insulating oil provides information about the overall condition of the transformer.
A transformer oil analysis offers:

Insulating oil analyses help to set priorities: For transformer management, the insulating oil in transformers is regularly sampled. The resulting data can be registered in a database for long-term comparison. Transformer asset managers use this documentation as a basis for planning and budgeting as well as for sustainable asset management.
