  • Apparatus and method for performing dissolved gas analysis on a piece of electrical equipment using resonant photo-acoustic spectroscopy and use thereof
    Patent number: 10365209
    Abstract: An apparatus is described for performing dissolved gas analysis on electrical equipment having components immersed in electrical insulating liquid. The apparatus comprises an analyzer including a photo-acoustic spectroscopy (PAS) measurement system for performing gas analysis on a gas sample wherein the PAS measurement system has an elongated channel including a resonant cavity and an electromagnetic energy source. The resonant cavity includes a first portion and a second portion configured for containing at least part of the gas sample, wherein the first portion defines an optical pathway configured for propagation of electromagnetic energy from the electromagnetic energy source. The resonant cavity includes an element configured for obstructing the propagation of the electromagnetic energy through to the second portion of the resonant cavity.
