MOST IMPORTANT ITEMS IN CIGRE D1


- 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.
