Furans in transformer oil
INTRODUCTION
Furans analysis together with oil soluble metal deactivator is an important analysis to monitor the degradation of winding insulation in the transformers. The presence of furans in transformer oils show the stage of the insulation degradation and a need of transformer replacement.
ABSTRACT
Determination of five furan degradation markers – 5-hydroxymethyl-2-furaldehyde (5HMF), 2-furfuryl alcohol (2FOL), 2-furaldehyde (2FAL), 2-acetyl furan (2ACF) and 5-methylfurfural (5MEF) – together with both Ciba® Irgamet® 39 passivator isomers on an ARION® Plus C18, 3.0 µm column (150 mm × 4.6 mm, ARI-5720-IK46). Mobile phase 20 mM ammonium acetate, pH 8.5 (ammonia) / ACN 80/20 (v/v) at 1.0 ml/min and 30 °C, UV detection at 220 and 275 nm. All seven peaks are resolved in under 9 minutes from a mixture of furans and passivator in water.
