GE HYDRAN M2

The GE HYDRAN M2 is an online transformer monitoring system from General Electric (GE). It is mainly used for real-time monitoring of dissolved gas (DGA) in oil in the transformer, and evaluates the insulation status of the transformer by analyzing the change

of gas composition, so as to warn potential faults in advance and avoid power failure caused by transformer failure.

Product name resolution
GE (short for General Electric) is a global technology company.
HYDRAN M2 is the name given by GE for this series of transformer online monitoring

systems, M2 stands for product model.
Product description
The HYDRAN M2 is a compact in-line monitoring device that is typically mounted on a transformer tank. It monitors the concentration of hydrogen, ethylene, ethane, methane and other gases in transformer oil through sensors in real time. Through the analysis of the components of these gases, the types of faults such as insulation deterioration, overheating and partial discharge can be judged, thus providing a basis for the maintenance of the transformer.
