GE Grid Solutions Kelman Transport X² Portable Onsite DGA

GE Grid Solutions  Kelman Transport X² Portable Onsite DGA

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.

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:

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
