Kelman DGA 900

Kelman DGA 900
GE’s new Kelman DGA 900 is 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.

Applications

The Kelman DGA 900 is an invaluable foundational tool for implementing Asset Performance Management (APM) across electrical generation, transmission and industry, enabling a condition based asset replacement strategy and delivering improvements in system reliability and availability.

A DS-Agile™ and PREDIX™ Grid APM ready device, the DGA 900’s wide range of communication methods and protocols enables connection to those platforms and integration with GE’s Perception™ transformer fleet management software as well as other software, historian and SCADA systems.
