Circularity
 the smaller the
circle, the better
 innovation is
needed for a
sustainable future
Measurement for Maintenance
Measurement for Maintenance
Problem
• The process of ageing is unknown.
• Hence remaining lifetime is unknown.
• To increase circularity, the asset should be used as long as possible.
• Current load and load capacity need to be known (Tiedo Tinga – load vs. load
capacity).
Solution
• measurements to increase understanding of ageing process:
- oil quality
- oil temperature
•
•
•
- outside temperature
- electrical load (mean and peaks)
10 transformers per age group of different capacities and types
no exchange of these transformers, but add a redundant one to maintain reliability
this also allows to overload transformers to increase ageing
- with every 6 degrees increase in hotspot temperature, the ageing rate doubles
Innovation Incentives
Problem
• The manufacturer does not have a constant incentive to increase sustainability
• Hence innovation is mainly related to the procurement process
• Without innovation, a sustainable future cannot be reached
Solution
• Cooperation through the supply chain by shared KPIs (Henk Akkermans & Simme
Douwe Flapper)
• What KPIs to measure?
– circularity
– energy efficiency
– reliability
•
This gives IEO the possibility to come with a business case to replace old
transformers for innovative ones (Jan Braaksma)

Design for circularity
Innovation Playground
Problem
• Conservative business while innovation is needed
• Reliability may not suffer as a result of innovation
• Innovations are needed to increase sustainability
• Pilot studies can prove the reliability of innovations
Solution
• innovation playgrounds with redundant transformer
• automatic switching in case of failure (with sensor equipment)
• redundant transformer may be used to regulate loads on the transformer
• design for maintenance and sustainability (Leo van Dongen & Wienik Mulder)
- measurement equipment
- reliable
- energy efficiency
- modular design (repleaceable windings/coils)
- oil replacement
- icebergs: on-load-tap-changer, 10kV to 20kV, energy storage (Richard Ruitenburg)
