This project is assessing the use of FR3 vegetable oil, manufactured by Coopers, as an alternative to mineral oil in large power transformers. FR3 is biodegradable and has a considerably higher flash point than mineral oil, however its increased viscosity and oxidisation rate means that additional design work is needed in the manufacture of the transformer.
The demonstration aims to:

  • Evaluate the use of FR3 as an environmentally friendly and safer alternative to mineral oil insulation of 132kV transformers

  • Assess the reaction of the plant components to FR3 and the comparative ageing of transformers with FR3 versus mineral oil.
