PD IEC TR 63025:2021
This standard PD IEC TR 63025:2021 Insulating liquids. Quantitative determination of methanol and ethanol in insulating liquids is classified in these ICS categories:
- 29.040.10 Insulating oils
This document specifies two test methods for methanol and ethanol determination in insulating liquids.
Methanol (MeOH) and ethanol (EtOH) are two light alcohols generated during the degradation process of cellulosic materials. They are soluble in insulating liquids so they can be regarded as ageing tracers whose concentrations in oil reflect the degradation of insulating cellulosic materials in liquid-impregnated transformers.
