]]> IEC 62770:2013 describes specifications and test methods for unused natural esters in transformers and similar oil-impregnated electrical equipment in which a liquid is required as an insulating and heat transfer medium. Natural esters with additives are within the scope of this standard. Because of their different chemical composition, natural esters differ from insulating mineral oils and other insulating fluids that have high fire points, such as synthetic esters or silicone fluids. Natural, ester-derived insulating fluids with low viscosity have been introduced but are not covered by this standard. Pertinent properties of such fluids are given in Annex B. This standard is applicable only to unused natural esters. Reclaimed natural esters and natural esters blended with non-natural esters fluids are beyond the scope of this standard.

Oils with and without additives are within the scope of this standard. Such oils will have originally been supplied in compliance with a recognized unused mineral insulating oil specification. This standard does not differentiate between the methods used to recycle mineral insulating oil. This standard does not apply to mineral insulating oils used as impregnates in cables or capacitors.

Scope

This International Standard is applicable to specifications and test methods for unused mineral insulating oils (see Clause 3 for definitions). It applies to oil delivered to the agreed point and time of delivery, intended for use in transformers, switchgear and similar electrical equipment in which oil is required for insulation and heat transfer. These oils are obtained by refining, modifying and/or blending of petroleum products and other hydrocarbons.
Oils with and without additives are both within the scope of this standard.
This standard is applicable only to unused mineral insulating oils.
Recycled oils are beyond the scope of this standard.
NOTE Definitions and specifications for recycled oils will be covered by IEC 627011.
This standard does not apply to mineral insulating oils used as impregnants in cables or capacitors.
