Standard Test Method for Furanic Compounds in Electrical Insulating Liquids by High-Performance Liquid Chromatography (HPLC)

Importancia y uso:

5.1 Furanic compounds are generated by the degradation of cellulosic materials used in the solid insulation systems of electrical equipment.

5.2 Furanic compounds which are oil soluble to an appreciable degree will migrate into the insulating liquid.

5.3 High concentrations or unusual increases in the concentrations of furanic compounds in oil may indicate cellulose degradation from aging or incipient fault conditions. Testing for furanic compounds may be used to complement dissolved gas in oil analysis as performed in accordance with Test Method D3612.
