Enhancing the Insulating and Thermal Reliability of Synthetic Ester Insulating Fluids Using SiC Nanoparticles
What if High Voltage transformer dielectric liquids could be both greener and significantly more powerful?
As the power industry pushes toward sustainable solutions, simply replacing mineral oil isn’t enough; we need dielectric liquids that perform better under electrical and thermal stress. In our latest work, published in IEEE Transactions on Dielectrics and Electrical Insulation, we show how a tiny addition of SiC nanoparticles can make a big difference.
🚀 Key highlights:
- Up to +35% improvement in dielectric strength
- Around +70% increase in thermal conductivity at 90°C
- Enhanced resistance to partial discharge activity
By engineering synthetic ester nanofluids at the nanoscale, we unlock a new class of high-performance, eco-friendly insulating media for next-generation High Voltage systems. This research is part of the NEUROSES project (Project No. 23389), funded by the Hellenic Foundation for Research and Innovation (H.F.R.I.).
🌍 Smarter insulation. Longer lifetime. Greener grids.
We would like to congratulate the team for this amazing work: K. Koutras, M. Pitsikalis, E. Pyrgioti, T. Tsovilis!
Best Poster Presentation Award at IEEE IAS 2025
We are honored to announce that our PhD Candidate, Michail Pitsikalis, received the Best Poster Presentation Award at the prestigious 2025 IEEE Industry Applications Society Annual Meeting in Taipei, Taiwan—one of the flagship global events in the field of electrical and power engineering.
Our awarded paper, “Effect of SiC Nanoparticles Size and Concentration on the Partial Discharge Behavior and Dissipation Factor of Synthetic Ester Oil,” co-authored by M. Pitsikalis, Dr. K. Koutras, Assist. Prof. G. Peppas, Prof. E. Pyrgioti, and Assoc. Prof. T. Tsovilis, presents cutting-edge research on advanced dielectric nanofluids for high-voltage applications.
This collaborative work between the Technical University of Crete, University of Patras, and Aristotle University of Thessaloniki (AUTH) is part of the NEUROSES project (HFRI Grant No. 23389), funded by the ΕΛΙΔΕΚ (H.F.R.I.).
This international recognition highlights our team's dedication to developing the next generation of sustainable, high-performance insulation systems for modern power grids.
