How to increase the environmental performance of your transformer systems with bio-based and recycled transformer oils from Nynas. The user example with distribution transformers from Rauscher & Stoecklin
The gap between what is really achieved and all the net zero scenarios already available will depend on the speed of our actions. However, there is no doubt that we need to act sooner rather than later to limit global warming. The electrical infrastructure is playing a leading role in this decarbonization effort, growing, and diversifying every day, with electrical transformers playing a crucial role. A transformer with a higher carbon footprint has higher shadow costs, and these costs should also be considered by the ultimate owner when buying, operating, or refurbishing an electrical transformer. Along this presentation we will discuss how environmental cost indicators are starting to be introduced or can be introduced in the procurement processes.
To simultaneously maximize performance and minimize the transformer’s environmental impact, Nynas has launched two new transformer liquids with enhanced sustainability credentials. The Nytro® BIO 300X - a bio-based hydrocarbon oil with an ultra-low viscosity - and the Nytro® RR 900X which is a re-refined oil with the same lifetime as a virgin oil. Both will be reviewed in detail, although there is no single transformer liquid to address all societal goals; the choice depends, as always, on multiple aspects. However, it is crucial that the classic return on investment indicators start to be adapted to include use-phase, end-of-life, and the referred shadow costs. The best part of the news is that solutions already exist; they are not under research, they are market-ready, and the clock is ticking louder and faster than ever. Rauscher & Stoecklin took the front seat and will showcase an example of a new product line of distribution transformers immersed in Nytro® BIO 300X
