Abstract

Analyses of dissolved gas and furfural in the insulating oil are a very efficient tool for assessing the working conditions of transformer. We propose the in-situ transformer health diagnosis without the need for oil sampling by measuring the Raman signals from C2H2 and furfural concentrations present in transformer oils. Raman signals in oil at ~1972 cm-1 and ~1705 cm-1 originating from C2H2 and furfural, respectively, were detected. The results show that laser Raman spectroscopy is a useful alternative method to diagnose the transformer faults.
