\u201cAs the transformer is located near a source of drinking water<\/strong>, we needed to make absolutely sure that no oil is spilled in the area, and we needed to use an insulating liquid<\/strong> that is highly Developed as an alternative to mineral insulating oil<\/strong> and ester liquids<\/strong>, NYTRO\u00ae BIO 300X<\/strong> offers a highly sustainable option. Produced from hydrocarbon by-products<\/strong>, it actually has a negative carbon footprint.<\/strong><\/p>\n G\u00f6teborg Energi decided to test the performance of NYTRO\u00ae BIO 300X<\/strong> by using it in one of three identical 40 MVA transformers<\/strong> installed in Gothenburg.<\/strong><\/p>\n \u201cThis enabled us to evaluate and confirm some of the features promoted by Nynas<\/strong>,\u201d Ferruccio Vuinovich<\/strong> says.<\/p>\n Already when filling the transformer during the Swedish mid-winter<\/strong>, the benefit of the bio-based liquid\u2019s<\/strong> ultralow viscosity was immediately evident.<\/p>\n \u201cThe low viscosity, even at low temperature<\/strong>, made it very easy to handle. It was almost like filling the transformer with water<\/strong>,\u201d he says.<\/p>\n However, the application-beating low viscosity of NYTRO\u00ae BIO 300X<\/strong> also provides enhanced cooling in the transformer. This too was evident in G\u00f6teborg Energi\u2019s transformer.<\/strong><\/p>\n \u201cWe have been able to achieve around 10 degrees lower temperatures<\/strong> in the transformer<\/strong>, improving the performance without the risk of overloads. It also opens the potential of using smaller transformers in certain locations. This is something we might look into in the future,\u201d<\/em> says Ferruccio Vuinovich.<\/p>\n The fact that NYTRO\u00ae BIO 300X<\/strong> is fully renewable<\/strong> and recyclable is obviously<\/strong> also important for G\u00f6teborg Energi<\/strong>, as the utility has set tough sustainability targets<\/strong> for its operations.<\/p>\n \u201cWith Nynas\u2019 NYTRO\u00ae BIO 300X,<\/strong> the sustainability improvement of the transformer can be combined<\/strong> with an improved performance. The innovation supports transformer operators like G\u00f6teborg Energi by enabling their equipment to fulfil stringent environmental<\/strong> needs, and also by lower Total Cost of Ownership<\/strong> of the transformer,\u201d comments Koen Kempeneer<\/strong>, Market Manager Electrical Industry, Nynas.<\/p>\n![\"\"](\"https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2021\/04\/nytro-bio-300x-fulfilling-promises-in-gothenburg-sweden.jpg\")
