Portable DGA analyser
Portable DGA analyser
(OP)
I’m currently working on a small project to recomend a portable DGA analyser for testing substation transformer oil. I have found information for a Kelman Transport X unit. Does anyone else use this piece of equipment and are you getting good results with it. Also what other units are available and what’s their performance like?
Cheers

RE: Portable DGA analyser
The main benefit of this machine we saw was to give an analysis of a transformer after a fault onsite, and to have fairly relaxed limits for pass or fail. Then you would take a sample back to the lab to be done for comparison purposes against previous gas readings.

Its an excellent device which is maintenance free when you compare it with a GC. Moreover, unlike GC, Kelman PAS technology has made DGA a very portable and compact instrument. It can be easily moved around.
I also agree with ausphil that its an ecellent device for continuous monitoring or trending. Even otherwise it is good. As far as i remember it comes with Key gases + moisture combination.
It is also important that you buy the complete analysis software of Kelman which will make your life easy. It can assist you in analysing results based on IEEE key gas method, Duval traingle and other techniques.
