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.
Cutting Edge Technology
- Five gases plus moisture in a single monitor
- Automated headspace gas extraction and state of the art photo-acoustic spectroscopy (PAS) measurement technology
- No carrier or consumable calibration gases required
- Brak konieczności używania gazów do kalibracji i gazów będących nośnikami
- Capable of sampling frequency up to once per hour or user defined sample rates
Ease Of Use
- Easy installation: no outages required, reducing expense and inconvenience for user
- Łatwa wymiana na zaawansowany monitor dziewięciu gazów TRANSFIX w przypadku wykrycia poważnych zagrożeń
- Easily swapable for a high end Kelman DGA 900 nine gas monitor, once serious issues are detected
- Over two year’s worth of data stored internallyat six-hourly sampling rate
Configurable Alerts
- Widoczne w świetle słonecznym tablice diodowe LED znajdujące się na przednim panelu
- Six user configurable alarm relay contacts
- Alarms can be set on gas or moisture ppm levels or on rate of change (ROC)
- Alarms can be set or changed locally or remotely using Perception™ software
- Caution and alarm modes can be used to automatically increase sampling frequency
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
