KELMAN DGA 900

Kelman DGA 900
Next generation on-line multi-gas DGAProven Technology
Dissolved Gas Analysis (DGA) and moisture measurement of insulating fluids are recognized as the
most important tests for condition assessment of transformers. In previous years, multi-gas DGA was
traditionally confined to a laboratory environment, with infrequent off-line manual sampling forming
part of time-based maintenance strategies. However, as the global average age of transformers
continued to rise, the possibility of rapid ageing, unplanned outages and even catastrophic failure
between off-line tests also increased, leading many asset owners to adopt on-line DGA monitoring
strategies to increase network reliability.• 4th generation of GE’s PAS technology delivering
improved accuracy with lower detection limits
In the early 2000’s, GE’s Kelman™ range of analysers brought consumable-free on-line multi-gas DGA
to the market and GE is now proud to introduce the Kelman DGA 900, our next generation multi-
gas on-line DGA and moisture analyser. At its heart lies an evolved implementation of GE’s proven
Photo-Acoustic Spectroscopy (PAS) measurement technology, providing laboratory challenging levels
of precision and repeatability with no consumables and no need for frequent re-calibration. Benefiting
from over 40 years of global DGA vendor experience, the Kelman DGA 900 encapsulates learnings
and improvements derived from its predecessors to bring improved performance, innovative new
features, enhanced user experience and increased robustness.
