GE Kelman TRANSPORT X Portable Dissolved Gas Analyzer
The Kelman TRANSPORT X is a compact portable dissolved gas analysis (DGA) system that analyzes transformer oil samples on site for dissolved fault gases and moisture. Instead of sending samples to a remote laboratory and waiting for results field crews can get gas readings on the spot along with a diagnostic if abnormal levels are found. It is built on photo acoustic spectroscopy (PAS) the same technology GE uses across its Kelman DGA range and the Kelman brand is now part of GE Vernova.
Key Features
- Photo acoustic spectroscopy (PAS) measurement: a calibration free technique that does not need consumable carrier gases
- Complete fault gas and moisture analysis: measures the key dissolved gases in transformer oil, including hydrogen, methane, ethane, ethylene, and acetylene, plus water in oil
- Automated headspace gas extraction: the instrument extracts the gases from the oil sample automatically, with oil and Buchholz gas introduced by syringe
- Built-in diagnostics: interprets results using IEEE/IEC-approved methods including ratio methods, key gas, and Japanese ETRA
- Buchholz relay gas analysis: analyze gas collected from Buchholz relays with a 5 ml gas sample, using the optional collection kit
- Companion to online monitors: a good partner to single gas online DGA monitors giving a full gas breakdown when an alarm is raised
- Gas check kit option: verify the instrument accuracy over time
- Software included: TransportPro PC software stores and exports results and Kelman PERCEPTION software is supplied for trending and analysis
- Connectivity and printing: USB computer interface and a built in thermal printer for hard copies on site
- Field ready: about 50 ml of oil per sample an operating range of 5 to 40 °C, and EMC testing to EN 61326-1 and related standards
Typical Applications
- On site health checks of power transformers
- Immediate diagnosis after an alarm from an online gas monitor
- More frequent testing of aging or suspect transformers
- Analysis of gas collected from Buchholz relays
- Condition assessment for utilities and industrial transformer owners
Why Choose It
The TRANSPORT X puts DGA results in the hands of field crews within a short time of sampling so operators can decide quickly whether a transformer needs attention. Its calibration free consumable free design keeps field operation simple and running costs low.
