Programmer Connection, Parallel

For a parallel interface (MS-DOS programmer only)

connect the programmer to the top port connector on

the Bus Transmitter Module (IC697BEM713) as shown

in Figure 1.  Consult  Reference 2 for a description of

programming functions.

Serial Port

The 15-pin D-connector provides the connection to an

RS-485 compatible serial port as shown in Figure 3.

This port provides a serial connection to a Standard

Serial COM port, or to a Work Station Interface board

installed in the programming computer.

Squeeze the rack clips on the back of the cover

with your fingers to disengage the clip from the

rack rail and pull the board firmly to remove it

from the backplane connector.

Slide the board along the card guide and remove it

from the rack.

Controllers

The Hydran 201Ti can be connected to optional controllers to facilitate

communication with multiple units and create a local network.

• The Ci-1 controller is a one channel controller that replicates some of

the human interface functions (gas value display, alarm buttons). This is

ideal when the 201Ti is mounted out of reach on an upper valve of the

transformer. It also brings down the alarm relay contacts and the analogue

output for easier wiring.

• The Ci-C controller receives the gas ppm data from up to four 201Ti,

providing a single communication point for all four monitors. It has no

alarm relay or analogue output. This is ideal when protecting 3 single phase

transformers + 1 spare.

It is possible to “daisy-chain” up to 32 controllers or 201Ti through their RS-485

port. The maximum chain distance (all cables added up) is 1200m (4000ft). All

the 201Ti connected to any of the daisy-chained controllers can be accessed

through any controller in the local network, thus facilitating communication by

only having to fit one RS-232 modem for example.

Human Interface

• Backlit LCD display of gas information

• Keypad to stop unit and acknowledge alarms

• Compatibility with GE’s acclaimed Perception™

software to download, trend and analyze

transformer data

Mark IV Improvements

• Completely overhauled with improved sensor

durability, new electronic boards and power

supply to make it RoHS compliant while

increasing device reliability and capabilities

• Local USB port to replace the RS-232 port no

longer found on most field laptops

• Digital output of registers using Modbus®

protocol communication over isolated RS-485

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

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

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

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

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

• Small form factor, no moving parts, low maintenance, and support for APM software analytics,

enabling fleet level deployments

• Condition monitoring for a wide range of 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

• Providing critical transformer gas behavior data for Asset Performance Management (APM)

strategies, facilitating planning of site intervention and maintenance activities

• Supports a wide range of communication methods and protocols to enable easy and secure

integration with GE’s digital platforms including Perception™ transformer fleet management

software, DS Agile substation HMI, PREDIX™, and other APM software tools, historians and SCADA

systems

Enhanced Monitoring with Extended Sensor Life

When a transformer’s insulation system is overstressed, the oil and paper undergo chemical

degradation producing both hydro-carbon gases and moisture that dissolve into the insulating oil. This

increased ageing will shorten the transformer’s life, impact its reliability and in some cases can even

lead to catastrophic failures.

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

It provides 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 an extended sensor life.
