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.
