GE Hydran M2 transformer monitoring equipment

ydran M2 is a compact, permanently installed online transformer monitoring device that can alert personnel to ongoing fault conditions. It continuously monitors the combined value of various faulty gases (in ppm) or just the hydrogen value (depending on the purchased sensor). In addition, it also tracks the moisture content in the oil (with readings in %RH and ppm).

By adding additional sensors, the Hydran M2 can also calculate the mathematical model of the transformer in accordance with IEEE® and IEC® standards to provide more information about the transformer’s performance.

Benefits

Real-time hydrogen or compound fault gas monitoring system

Measurement of moisture in oil

It can integrate other sensors (load, oil temperature, etc.)

The transformer mathematical model based on IEC/IEEE standards can be optionally processed

Easy to install on a single valve.

No moving parts, no pumps, and no additional pipes are required.

No on-site calibration is required.

Local and remote alerts are set to predefined levels.

Feature

The hydrogen sensor responds 100% to hydrogen (the common fault gas)

The composite gas sensor has a 100% response to hydrogen and is also sensitive to carbon dioxide (overheated paper insulation).

Select up to 4 input or output cards

Extensive communication methods and protocols.

RS485 output is a standard configuration. TCP/IP copper cables or optical fibers are optional

Vacuum gas extraction membrane.

Built-in temperature condition system.

Self-check and self-diagnosis throughout the system.

Record data and major events for up to one year.

User-friendly client/server graphical user interface software.
