GE HYDRAN M2 Product Introduction

GE HYDRAN M2 is a compact,permanently installed online monitoring device that is mainly used to monitor the dissolved gas and moisture in the oil of the transformer,as well as other key parameters.By continuously monitoring these parameters,GE HYDRAN M2 can promptly issue an alarm when a transformer fails,thereby reducing the risk of unexpected power outages.

Main functions

Dissolved Gas Analysis(DGA)

Monitors fault gases dissolved in the oil,such as hydrogen(H2),carbon monoxide(CO),acetylene(C2H2)and ethylene(C2H4).

Provide composite gas sensor or hydrogen sensor only options,choose according to user needs.

Moisture in Oil Monitoring

Track the moisture content in the oil and read it in%RH(relative humidity)and ppm(parts per million).

Moisture monitoring helps identify degradation of insulation paper and leakage of gaskets.

Other parameter monitoring

Other sensors can be connected,such as top and bottom tank oil temperature,transformer load or ambient temperature,etc.

These parameters allow a deeper analysis of the transformer’s condition.

Technical features

Built-in mathematical model

A transformer mathematical model based on the IEEE standard provides transformer status information.

Model outputs include estimated winding hot spot temperature,humidity in paper,moisture bubbling temperature,insulation aging,overload capacity,cooling efficiency and OLTC temperature difference,etc.

Multiple communication options

Supports multiple communication methods and protocols,such as RS485,etc.

Simplifies integration with SCADA or DCS systems.

Easy to install and maintain

No additional pipes or pumps are required,easy to permanently install on a single transformer oil valve.

No moving parts,low maintenance cost.

Alarm and self-test function

Two alarm levels(alarm and alarm)are set to show increasing severity.

Automatic self-test every 15 days,triggering a service alarm when a fault is detected.

Product Advantages

Early fault detection:By continuously monitoring dissolved gas and moisture in oil,GE HYDRAN M2 can issue an alarm in the early stages of transformer failure,thereby reducing the risk of unexpected power outages.

Improve reliability:Provides a transformer mathematical model based on IEEE standards to help users gain a deeper understanding of the status of the transformer and improve the reliability of the equipment.

Easy to integrate:Supports multiple communication methods and protocols to simplify the integration process with existing systems.

Low maintenance cost:There are no moving parts,low maintenance costs,and reduced user operation and maintenance burden.

Application areas

GE HYDRAN M2 is widely used for medium-sized transformer monitoring in power facilities and industrial plants.It is an important part of the integrated solution,helping to reduce the risk of process interruptions due to power outages and minimize costly downtime.

In summary,GE HYDRAN M2 is a comprehensive,technologically advanced,easy to integrate and maintain online transformer monitoring device.It provides users with real-time status information of the transformer by continuously monitoring dissolved gas and moisture in oil and other key parameters,helping users to detect and deal with potential faults in a timely manner,thereby improving the reliability and safety of the equipment.
