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

Applications

Advanced, flexible and expandable DGA monitoring solution tailored for utility and industrial

transformers.

Easily integrates with Kelman multi-gas DGA devices and the Multilin 845 protection & control

relay to provide continuous synchronization of chemical and electrical measurements for enhanced

transformer monitoring

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.

When an unexpected failure of a critical transformer occurs, the operational and economical impacts

on the utility are substantial. Today, many existing oil-insulated transformers used by electrical utilities

and other industries are approaching the end of their design life and are experiencing significantly

higher probabilities of failures.

Prognastics and Diagnostics

The prognostics and diagnostics software module on the Intellix MO150 is designed to provide

guidance whenever an alarm condition is present. It is intended to provide the first level of awareness

of what the alarm condition is all about, what the alarm condition means and what steps or actions

could be taken to improve the current situation.

The module will provide:

• Diagnostic: Identification of the alarm and/or set of alarm conditions.

• Prognostic: A set of statements that warn the operator about the  possible consequences for the

transformer if the situation is allowed to continue without any remedial action being taken.

• Recommendation: Summarizes the verifications that could be carried out, data that could be

collected to facilitate further actions and specific actions that could improve the current situation.

The Ethernet Interface module (IC693CMM321) provides an interface that allows you to attach the

Series 90-30 PLC to an Ethernet LAN via an external transceiver and AAUI cable, and to

communicate with hosts and other control devices on the network.

The Ethernet Interface for the Series 90-30 PLC has client/server capability.  As a client it can

initiate communications with other PLCs containing Ethernet Interfaces.  This is done from the

ladder program using the COMMREQ Function Block.  As a server it responds only to requests

from other devices such as a Host computer running a Host Communications Toolkit application or

another Series 90-30 PLC acting as a client.

The Ethernet Interface allows you to:

Directly attach your PLC to an Ethernet network

Initiate transfer of data to the PLC from another device

Communicate simultaneously to multiple devices with up to 16 server connections

Interface with other GE Fanuc devices, as well as with devices from other vendors

Communicate from a Host computer (or other control device)

Diagnose and maintain your system using diagnostic and station management tools

The Ethernet Interface does not support the Series 90-30/20/Micro Hand-Held Programmer. 

Either one or two Ethernet Interface modules can be installed in any Series 90-30 baseplate.

The Ethernet Interface connects to an Ethernet network through an external SQE enabled

transceiver (GE Fanuc catalog no. IC649AEA102 or IC649AEA103 or equivalent.

See AppendixJ).  The following figure shows the layout of the Ethernet Interface.

The ELFD Controller Carrier provides a mounting platform for up to two SafetyNet Controllers (8851-LC-MT) .

It can also accommodate a Power Supply Monitor module (8410-NS-PS)

which can monitor the health of up to two 8913-PS-AC,

four 8914-PS-AC power supplies and the 12V supply to Intrinsically Safe Modules (when these are used) .

For each Controller there is a serial port connector and a manually operated ““Change State” button .

The Carrier also provides terminals that are used when earth leakage fault detection is required.
