Popis

BS EN IEC 62770:2024


This standard BS EN IEC 62770:2024 Fluids for electrotechnical applications. Unused natural esters for transformers and similar electrical equipment is classified in these ICS categories:
  • 29.040.01 Insulating fluids in general
IEC 62770:2024 describes specifications and test methods for unused natural esters in transformers and similar liquid-immersed electrical equipment in which a liquid is required as an insulating and heat transfer medium. The exposure of natural ester to air leads to deterioration of the insulating liquid. Use of natural esters is therefore restricted to sealed units, or with the conservator tank protected from the contact with atmosphere by a membrane or other suitable system.
