RX3i Universal Backplane Installation

The RX3i system and its components are considered open equipment (having live electrical parts that may be

accessible to users) and must be installed in a protective enclosure or incorporated into other assemblies

manufactured to provide safety.  As a minimum, the enclosure or assemblies must provide protection equivalent to a

NEMA/UL Type 1 enclosure or an IP20 rating (IEC60529). The enclosure must be able to adequately dissipate the

heat generated by all of the components mounted inside so that no components overheat.  A minimum space of at

least 102mm (4 inches) as shown below is required on all sides of the RX3i backplane for cooling.  Additional space

may be required, depending on the amount of heat generated by the equipment during operation. Please refer to the

PACSystems RX3i System Manual, GFK-2314. for information about enclosures and heat dissipation.

Backplane Orientation

Backplanes must be mounted horizontally to meet product

performance and reliability specifications by providing

adequate airflow around the modules.  Other mounting

orientations may affect system performance and/or reliability

and are therefore not recommended.

The PACSystems* RX3i Universal Backplanes provide a dual-bus backplane that supports PCI-based

(IC695) and serial (IC693 and IC694) I/O and option modules. The RX3i Universal Backplanes also

support Series 90-30 IO and option modules.  See the PACSystems RX3i System Manual, GFK-2314 for

lists of supported modules. The 16-slot Universal Backplane (IC695CHS016), and the 12-slot Universal

Backplane (IC695CHS012) include the following features:

▪ Terminal Strip on the left end for Isolated +24V input

▪ Backplane grounding point

▪ An integral grounding bar for connecting module/shield grounds

▪ Serial Expansion connector for connection to Serial Expansion and Remote Backplanes

▪ Slot numbers printed on the backplane that can be used as a reference for configuration.

The 12-slot Universal Backplane (IC695CHS012) is illustrated below.

Application Example

The Kelman Transport X² remains your ideal partner for use in conjunction

with GE’s range of single gas online DGA monitors. These units (such as

Hydran™ 201Ti and Hydran M2-X) monitor the transformer and raise an

alarm when an abnormal level of fault gas is reached or when the rate of

change of this gas level increases rapidly so that you can take action and

protect your transformer early in the process.

Such events often require further investigation before a valid conclusion

can be reached. Traditional methods require an oil sample to be sent to a

laboratory for analysis. This can be a lengthy process before a diagnosis

and related decision can be made. However, with the Transport X², the

sample can be taken and analyzed onsite, giving comprehensive diagnostic

information in less than 30 minutes. The Transport X² data can then be

uploaded and visualized in GE’s powerful Perception software alongside  the

readings from the online monitor.

Key Benefits

• Measurement of seven diagnostic gases and moisture content in the oil

• Fast diagnostics in less than 30 minutes

• Intuitive touchscreen interface with step-by-step instructions and Plug and Play connectivity

• Compatible with mineral insulating oils and newer ester-based fluids (natural and synthetic)

• Enables operators to effectively respond to alarms, trip events and supports on-site field decision making

• Ideal companion to GE’s range of single gas online DGA monitors for adding transformer diagnostics

Applications

As the average age of generation, transmission and distribution transformers increases, the risk of rapid

deterioration and even catastrophic failures also increases. Transformer changes can occur in between

rounds of periodic laboratory DGA analysis and this risk exposure can go unnoticed. The Transport X² offers

electric utility and industrial customers accurate, economical and portable DGA and diagnostics in an easy

to-use handy instrument that is applicable for:

• Mission critical industrial transformers

• Distribution transformers

• Buchholz relay gas

• Tap changer tanks

• Instrument transformers

• Oil filled circuit breakers

Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids are recognized as the most

important tests for condition assessment of fluid-insulated transformers. Every year asset owners deploy

field crews to take thousands of fluid samples from transformers as part of periodic health checks and for

immediate operational decisions. These samples are sent to offsite laboratories for analysis.

Kelman™ Transport X² is a portable ‘lab in a box’ delivering detailed analysis with dramatically reduced

turnaround times. In critical situations, the ability to perform DGA in less than 30 minutes on the spot,

empowers asset owners to determine a transformer’s condition onsite and thereby allow operational

decisions to be made at the earliest opportunity.

GE was the first to deliver consumable-free DGA products to the market and the Transport X² represents

the next generation of its portable system. GE’s class leading Photo-acoustic spectroscopy (PAS) gas

measurement technology, now in its fourth generation, provides laboratory-challenging levels of precision

in a calibration free, easy-to-use and hand-carriable product.

Benefiting from over 40 years of global DGA experience, the Transport X² encapsulates intuitive

advancements to bring improved performance, innovative new features, enhanced user experience and

greater robustness.

Subsystems like the tap changer, the cooling system or the bushings can generate their own problems if they are left unmonitored.

The DGA 900 PLUS monitoring system integrates DGA measurement, additional sensors,

analysis models and data handling features to address the majority of prevalent failure modes.

This cost-effective package provides the condition assessment tools essential for the effective

management and optimal utilization of this critical sub-station asset.

It is most suited for monitoring large, mission critical transformers or compromised transformers

with a view to extending their life and preventing any unexpected failure:
