The GE HYDRAN M2 Module is a continuous on-line dissolved gas monitoring solution that provides real-time monitoring of fault gases and moisture in transformer oil.

Product Description

The HYDRAN M2 Module is designed to fit into a HYDRAN unit for continuous monitoring of dissolved gas and moisture levels in transformer oil. It uses a proprietary gas chromatography method to accurately detect and measure fault gases and moisture in real-time. The module can be configured to monitor up to 5 dissolved gases plus moisture, including hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ethylene (C2H4), and moisture (H2O).
