MOST IMPORTANT ITEMS IN CIGRE D1
SC-D1 Materials & Testing
- New insulating liquids (natural and syntethic esters), especially for
distribution transformers (Project EDF). Implication on the insulating
papers in case of higher viscosity liquids, like the esters;
- Use of additives in insulating liquids (antioxidants, metal passivators,
antigassing, etc). Declaration of additives, chemicals (REACH) and
environmental impacts;
- UHF Testing for transformers and interferences;
- UHF Testing and correction factors. Altitude factor. The case of the
insulators (Pigini, IT) and heavy wetting factors. New factor (Li, AU) like
high temperature factor.
