GE HYDRAN M2 Product Overview

GE HYDRAN M2 is a compact,permanently installed online transformer monitoring device designed to provide critical monitoring information to detect potential problems early when a transformer fails and minimize the risk of unexpected power outages.The following is a detailed introduction to GE HYDRAN M2.

Main functions and features

Continuous monitoring

Real-time monitoring of fault gases(such as hydrogen,carbon monoxide,acetylene,ethylene,etc.)and moisture content dissolved in transformer oil.

A choice of traditional”composite gas”sensors or more basic”hydrogen only”sensors.

Alarm function

When abnormal levels of fault gas or moisture are detected,an alarm will be sounded.

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

Data communication and integration

A variety of communication options and protocols are available to simplify integration with SCADA(supervisory control and data acquisition)or DCS(distributed control system).

Supports new low-flammability ester oils and mineral transformer insulating oils.

Transformer mathematical model

Built-in transformer mathematical model based on IEEE standards(only for mineral oil)to provide more in-depth status information.

Alarms can be set based on the values​​of the optional analog input card or calculated transformer model.

Easy to install and maintain

Easy to permanently install on a single transformer oil valve,no additional piping or pumps are required.

Automatic self-test every 15 days,triggering a service alarm if a fault is detected(such as power failure,oil valve closure,sensor failure).

Humidity monitoring

Humidity sensors measure moisture in the oil,helping to detect problems such as insulation paper degradation or gasket leakage.

Application scenarios

GE HYDRAN M2 is suitable for the following application scenarios

Power facilities:As an all-in-one solution for important medium-sized transformers,reducing the risk of process interruptions due to power outages.

Industrial plants:Provide continuous monitoring to minimize costly downtime.

Technical specifications and parameters

The technical specifications and parameters of GE HYDRAN M2 may vary depending on the specific model and configuration,but generally include

Sensor type:composite gas sensor or hydrogen sensor only.

Measuring range:fault gas(ppm),moisture(%RH and ppm).

Communication interface:Multiple communication options and protocols.

Alarm settings:Two alarm levels(alarm and alarm).

Self-check function:Automatic self-check every 15 days.

Maintenance and care

To ensure the long-term stable operation of GE HYDRAN M2,it is recommended to perform the following maintenance and care work regularly

Check the sensor:Make sure the sensor is clean,undamaged,and properly connected to the device.

Check the communication line:Make sure the communication line is unobstructed,undamaged or loose.

Regular calibration:Calibrate the device regularly according to the instructions in the device manual to ensure the accuracy of the measurement results.

Record and analyze data:Regularly record and analyze the data monitored by the device to detect and deal with potential problems in a timely manner.
