Abstract
The increasing global focus on environmental impact and sustainable development has generated a growing demand from materials and power equipment manufacturers and owners to make a positive contribution towards these aspects. In this regard, new insulating liquids such as Bio-based hydrocarbon and Gas-to-Liquid (GTL) insulating liquids have been analyzed in this study, considering their biodegradation rate and technical characteristics. Also, the possibility of reusing aged mineral oil is emphasized as this makes it possible to change unsustainable patterns of consumption and production, in close connection with the advantages offered by the circular economy and the efficient use of resources in a systemic, cyclical and prospective approach. Imperatively, the push to improve sustainability credentials does not signify compromising the functional properties of the insulating liquid. Therefore, this paper will not only play a significant role in assessing the impact of incorporating these dielectric insulating liquids into power transformers but also analyze the trade-offs in employing any of these insulating liquids. Furthermore, the extensive assessment of their properties is part of the broader initiative to support a transition towards environmental sustainability, safety, and reliability of high-voltage equipment.
