  • Is SF6 Dissolved in Your Transformer Oil? - Doble Engineering

    For example, dissolved SF 6 will cause some DGA monitors and portable analysers that use IR measurement methods (e.g. Photo Acoustic Spectroscopy, Non-Dispersive IR) to report false high readings for one or more key fault gases. So, unknown SF 6 in the oil may potentially lead to poor transformer maintenance decisions.
