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

    Also, SF 6 in the oil can complicate the Dissolved Gas Analysis (DGA) processes that are so important to transformer health assessment and maintenance decisions. 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.
