Environmental, Transformers and Electricity Transmission Networks
Our overall objective is to reduce the environmental impact of gas insulated transmission assets. The specific objective of this project is to identify potential gas mixtures involving NOVEC ™ that could offer the opportunity to replace SF6 in existing assets without needing to replace the whole asset with one that can withstand the higher pressures needed when using g3 ™ .
The successful development of a test system which can replicate typical fields found in 400 kV SF6 filled equipment.
To verifying the withstand ability of the alternative gas/gas mix under AC, lightning impulse (LI) and switching impulse (SI) voltages.
To develop the opportunities to further trial retrofit NOVEC filled switchgear both within the University and at the Deeside site.
