HYDRAN M2-X

HYDRAN M2 on-line monitoring system for faulty gas in transformer oil

General specification
Based on field-proven technology, the new Hydran M2 adds a mathematical model of the transformer based on IEEE® and IEC® standards to provide real-time transformer overview information. This is not only to monitor dissolved gas and humidity, but also to expand the monitoring of more failure forms of the transformer.

When an important transformer has an unpredictable failure, it will have a serious impact on the operation and economy of the power grid. Today, many oil-immersed transformers for power grids and industrial users are approaching the bottom line of their design life and show a significant increase in failure rates. Strict regulations on power supply, reduced budgets for investment and operating costs, and a shortage of specialized technicians all require extending the service life of these transformers.

Description
The Hydran M2 is an economical, powerful, all-in-one transformer monitoring device that allows power grids and other users to deploy monitoring of multiple transformers and benefit from its advanced features.

The Hydran M2 Early Failure Alarm model monitors early failure of transformers and other oil-immersed equipment with in-line failure gas and humidity sensors. Additional digital and analog inputs allow monitoring of other transformer variables. The new transformer model expands the monitoring and asset management capabilities of the Hydran M2, which provides more decision-making assistance to equipment operators and maintenance personnel.

• Isolated RS-232 serial interface in place
