| Abstract: | The principle to apply photoacoustic spectroscopy in the online monitoring of dissolved gasses in transformer oil is discussed. The way to measure hydrogen contentration with the velocity of sound excited by light is presented. The comparison between photoacoustic spectroscopy and online gas chromatography and online FTIR spectroscopy in detectable parameters and technical characteristics is made. |
