Hydra-m2 is a kind of on-line monitoring equipment, which is mainly used for on-line monitoring of transformer and other equipment. It has the following characteristics:
Powerful: The Hydra-M2 continuously monitors gas and moisture content to alert users to ongoing failures and minimize the risk of unplanned downtime.
Early failure warning: Monitor early failure of transformers and other oil-immersed equipment with in-line failure gas and humidity sensors.
Digital and analog inputs: Additional digital and analog inputs allow monitoring of other variables of the transformer.
Optimization and Low Maintenance: Build on GE's strong domain expertise to deliver optimized, low maintenance monitoring equipment.
Extended sensor life: The service life of the sensor is extended through advanced technology.
Overall, the Hydra-M2 is a powerful, easy to use and maintain online monitoring equipment, suitable for a variety of transformers and other equipment online monitoring.
Transformers are an expensive and critical component of the power grid, and the health of transformers is critical to building a reliable power grid.
When the insulation system of the transformer is under excessive pressure, gas dissolved in the oil will be produced. Dissolved gas analysis in oil (DGA) is recognized as the best indicator of fault development.
The HydranTM M2 is a continuously in-line dissolved gas and water in oil monitoring device that alerts in the event of transformer failure.
It provides critical monitoring information to minimize the risk of unplanned power outages.
By connecting additional sensors, such as top and bottom tank oil temperature, compressor load or ambient temperature, more information can be obtained and linked to DGA and moisture values for a deeper analysis of the transformer's condition.
This rich data can not only be transmitted raw through M2's wide range of communication options, but can also be converted into useful information by on-board calculations based on the IEE@ standard's mathematical model of the transformer, thus providing more status information.
Major advantage
- Continuous measurement of moisture in dissolved fault gases and oils to detect potential problems early before serious transformer failures occur
- Extend monitoring capabilities with additional sensors (load, oil temperature) and built-in calculations for transformer models based on IEEE standards
Multiple communication options and protocols, including IEC@61850, simplify integration with SCADA or DCS systems
- Third generation mature design, very large worldwide installation
- Support new low inflammable ester base oils and mineral transformer insulating oils

The functions of the Hydra-M2 include:
Gas monitoring: Gases in transformer or oil-cooled cable systems can be monitored, including hydrogen, acetylene, methane, ethane and ethylene. The formation and accumulation of these gases can be a sign of insulation failure.
Real-time monitoring: real-time monitoring of gas concentration changes, as well as oil temperature and pressure and other parameters. This helps identify potential problems early.
Alarms and notifications: When gas concentrations are detected to exceed a predetermined threshold, the Hydra-M2 emits an alarm, notifying the operator or maintenance personnel to take action. This helps reduce the risk of potential equipment damage or accidents.
Data recording and trend analysis: One year of local data and major events can be recorded, which is convenient for users to analyze faults and formulate preventive measures.
In addition, by connecting additional sensors, such as top and bottom tank oil temperature, transformer load or ambient temperature, the Hydra-M2 can also be captured and used to associate DGA and humidity values for more in-depth analysis of the condition of the transformer.
