Mark III  Hydran M2 GE

Transformers are key and expensive components of the electrical grid and knowledge of their health condition is essential to having a reliable network. When a transformer’s insulation system is overstressed, gases are produced that dissolve in the oil. Dissolved Gas-in-oil Analysis (DGA) is recognized as the best indicator of developing faults. The Hydran™ M2 is a continuous on-line dissolved gas and moisture in oil monitoring device that alerts personnel of developing fault conditions in their transformer. It provides key monitoring information and minimizes the risk of unplanned outages. Through the connection of additional sensors (for example top and bottom tank oil temperature, transformer load or ambient temperature), additional information can be captured and used to correlate with DGA and moisture values for a more in-depth analysis of the transformer’s condition. This wealth of data can, not only be transmitted raw using the M2’s wide range of communication options but can also be converted into useful information through the on-board calculation of IEEE® standard’s based transformer mathematical models in order to provide further condition information
