Transfix DGA 500
Automated five Gases plus Moisture Online DGA

The Transfix™ DGA 500 is an on-line monitoring unit that measures five individual dissolved gases and moisture, and provides both on-line monitoring and key exploratory diagnostics. It uses GE’s advanced Photo-acoustic spectroscopy (PAS) technology, made popular due to its accuracy, repeatability and lack of consumable through its bigger brother the Kelman™ Transfix.

The Transfix DGA 500 enables the well known Duval's triangle DGA diagnostic described in Appendix B of IEC Standard 60599 and integrates seamlessly with Perception to provide not only dashboard and risk information for the transformer monitored but also to compare that transformer's health with that of other similar assets and showcase its priority as part of the fleet management tool.

Key Benefits

  • Automated, on-line multi-gas and moisture monitoring
  • Provides early identification of arcing issues before they become critical failures
  • Ability to perform Duval’s triangle DGA diagnostic
  • Easily replaceable with a full nine gas unit
  • Communicates data to allow remote diagnostic
  • No carrier or calibration consumable gases required
  • Available with AC or AC/DC power supply


Power Utilities:

  • Middle of the road solution for medium-criticality transformers
  • Monitoring together with remote exploratory diagnostic
  • Industrial Plants:

    • Reduces the risk of process interruption due to power failure
    • Minimizes costly production downtime
