Qualitrol has 3 types of DGA: TM1, TM3, TM8
1. TM1
The Serveron® TM1 continuously monitors and reports hydrogen PPM Levels and can be programmed to alarm based on PPM Levels and/or Rate of Change (ROC), warning operators of potentially disruptive transformer faults and pending failures.
Features
- Responds only to Hydrogen: no cross interference or composite measurements.
- Rapid step change response facilitated by active oil circulation over the sensor itself.
- Single Valve mount
- Low Cost of Ownership:
- No Membrane – directly immersed sensor
- No Sensor replacement or recalibration required for life of monitor
- No Consumables or routine service required
Options
- Moisture-in-oil and oil temperature measurement.
- Qualitrol provides utilities with the following services for our on-line DGA monitors.
- Turnkey Installation Services including Serveron® TM1 deployment and TM View software user training
- Serveron® Monitoring Service (SMS) offers the convenience of secure 24×7 access to all of your Serveron® DGA transformer monitor data from any Internet-connected Windows PC running our SMS software.
- A variety of service plans to guarantee monitor operation over the long term
2. TM3
The Serveron® Model TM3 is the only transformer condition alert system in its class that offers legitimate identification of the most critical transformer fault types via Duval’s triangle. The TM3 will provide a laboratory quality set of DGA results every 4 hours and up to once per hour under active fault conditions. With TM3 you can simultaneously track DGA, moisture, temperature and load on your transformer.
Features
- Correlates 3 fault gases (acetylene, ethylene, and methane), moisture-in-oil, oil temperature and ambient temperature to transformer load
- The combination of on-line DGA data automatically populating the Duval Triangle provides unprecedented insight into fault diagnosis
- Our TM View software allows you to track and alarm on ppm and rate of change for the gases measured while at the same time providing for automatic diagnosis of developing faults using the powerful Duval Triangle algorithm
Options
- Moisture-in-oil and oil temperature measurement
- Integrated display
- Optional Interfaces: Cellular modem, Ethernet Copper (10/100Base-TX), Wireless Radio
- Serveron® TM3 installation and / or commissioning
- TM View software installation and user training
- A variety of service plans to ensure guaranteed analyzer operation over the long term
3. TM8
The TM8 will provide a laboratory quality set of DGA results every 4 hours and up to once per hour under active fault conditions. With TM8 you can simultaneously track DGA, moisture, temperature and load on your transformer.
Features
- Correlates all 8 fault gases, moisture-in-oil, oil temperature, and ambient temperature to transformer load
- TM View software provides powerful tools to manage your fleet of DGA transformer monitors, focusing attention on alarming assets and simplifying the analysis of data which warrants further review
- Automatic download of DGA data to a central database
- Graphing and trending of DGA data
- IEEE and IEC diagnostic tools such as Rogers Ratios, and the Duvals Triangles 1, 4 & 5 and Duvals Pentagon for advanced diagnostics
Options
- Moisture-in-oil and oil temperature measurement
- Integrated Display
- Optional Interfaces: Cellular modem, Ethernet Copper (10/100Base-TX), Wireless Radio
- Serveron® TM8 installation and / or commissioning
- TM View software installation and user training
- A variety of service plans to ensure guaranteed analyzer operation over the long term
