Anotácia textu normy IEC/TR 63025-ed.1.0 :

IEC TR 63025:2021(E) 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.
