Kelman TRANSPORT X2 portable DGA (Dissolved Gas Analysis) and moisture in oil

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

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


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
