A relevance index of importance for design and for service as well as the status of validation is given for all individual requirements (parameters). All parameters are assigned to one of the following categories:
  • General (physical / chemical)
  • Dielectric / Insulation
  • Thermal / Cooling
  • Ageing and Stability
  • Liquid-solid system
  • Material compatibility
The document is intended to serve as a general reference document for the transformer industry, including liquid suppliers as well as relevant scientific and technical bodies dealing with insulating liquids (materials).
