Easy Asset Supervision

• Permanently mounts on a single transformer oil

valve. No extra piping or pump required

• “Composite gas” sensor responds 100% to

Hydrogen (general fault gas) and is also sensitive

to Carbon Monoxide (overheated paper)

Acetylene (arcing) and Ethylene (overheated oil)

thus covering main failure root causes

• “Hydrogen only” gas sensor is simpler and

responds 100% to Hydrogen gas only, the

general fault gas

Configurable Alarms

• An alarm is raised when an abnormal level of

fault gas is detected

• Two alarm levels (one for Alert and one for Alarm)

can be set to show increasing severity

• Alarms can be set on gas ppm levels or on gas

rate of change (ROC) over an hour or a day

• Automatic self-test every 15 days will trigger

service alarm if it detects a fault, including power

failure, oil valve closed, sensor or  battery needing

replacement

Applications

Power Utilities

• Simple and effective solution for less-critical transformers

• Focuses and prioritizes asset replacement strategy

Industrial Plants

• Reduces the risk of process interruption due to power failure

• Minimizes costly production downtime

The 201Ti uses fuel cell technology (described as fixed instruments – method 3 in the standard) and is

now available with a choice of either the world renown “Hydran Composite Gas” sensor which responds

100% to Hydrogen and is also sensitive to Carbon Monoxide, Acetylene and Ethylene or the more basic

“Hydrogen Only” sensor which focuses purely on Hydrogen gas generation.

Because the monitoring unit mounts on a single valve and uses Dynamic Oil Sampling, there is no need

for a pump or extra piping to connect to different valves. Due to its uncomplicated features and the easily

understood information it provides, the 201Ti has been amongst the monitors of choice for many years,

with one of the largest installed base of any DGA monitor.

Key Benefits

• Continually measures key fault gas to give you an insight into the transformer’s condition

• Choice of gas sensor: traditional “Composite gas” or more basic “Hydrogen only”

• Communicates gas ppm and gas rate of change values remotely to avoid site visits and enable

remote supervision

• Fourth generation of this continuously improved design, with over 25.000 units sold worldwide

Essential DGA monitoring for transformers

Transformers are key and expensive components of the electrical grid and knowledge of their

health condition is essential to having a reliable network. When a transformer’s insulation system is

overstressed, gases are produced that dissolve in the oil. Dissolved Gas-in-oil Analysis (DGA) is recognized

as the best indicator of developing faults.

The Hydran™ 201Ti is a small and easy to setup continuous Dissolved Gas-in-oil Analysis (DGA) monitor.

It provides the basic information used by IEEE® Standard C57.104 and can be used as an essential first

line of defence for the transformers in your fleet to obtain advance warning of a failure condition and

minimize the risk of an unplanned outage.

The 201Ti uses fuel cell technology (described as fixed instruments – method 3 in the standard) and is

now available with a choice of either the world renown “Hydran Composite Gas” sensor which responds

Features

Easily upgradeable in the field to accept analog signals and monitor other key transformer parameters

Computation of winding hot spot and other IEEE transformer models for enhanced diagnostics

of the transformer’s condition (depending on sensors installed)

Easy to install on a single existing transformer valve, often without an outage required

Integrated display and keypad for simplified local user interaction and data visualization

Built-in moisture sensor provides water in oil measurement, critical to identify paper degradation and leaking gaskets

Compatible with GE’s acclaimed Perception™ software to download, trend and analyse transformer health data

Applications

Medium to large sized transformers

Utility and industrial transformers

Transmission transformers

Key Benefits

Small form factor, no moving parts, and low maintenance

Support for Asset Performance Management (APM) software analytics, enabling fleet level deployments

Condition monitoring for transformers with mineral insulating oils or ester based fluids (natural and synthetic)

Extending beyond DGA monitoring, through the connection of sensors, the Hydran M2-X can monitor

other parameters such as top oil temperature, load current and through the use of IEEE based mathematical models,

can provide further insight on changing transformer conditions

Provides critical data for APM strategies, facilitating planning of site intervention and maintenance activities

The M2-X-HZ version is certified for hazardous locations where ignitable concentrations of flammable gases,

vapors or liquids are not likely to exist under normal operating conditions but where the risk still exists.

The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions,

providing continuous monitoring of gas and moisture levels to alert users of developing faults and minimize the risk of unplanned outages.

The M2-X builds on GE’s strong domain expertise to deliver an optimized,

low maintenance monitoring device with extended sensor life.

The Hydran M2-X is also available in a UL certified, HazLoc version (part number: M2-X-HZ)

for installation on transformers located in hazardous locations designated as Class I, Division 2

The Hydran sensors are available as a traditional Hydran composite gas (H2. CO, C2H2. C2H4) sensor or a discrete Hydrogen only (H2) sensor.

In addition, it tracks moisture in oil (reading in %RH and ppm) and is compatible with various transformer oil types

(standard mineral insulating oils and newer natural and synthetic ester based fluids).
