Kelman DGA 900

Multigas system to replace DGA monitoring

The Kelman™ DGA 900 is an 9-gas on-line transformer DGA monitoring unit. Using our 4th generation of advanced photo-acoustic detection technology, the DGA 900 measures all significant fault gases (in ppm) as outlined by international standards as well as moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect and diagnose a complete range of transformer faults.

Reliable and Available

    • Key Benefits

    • Provides remote alert and multi-gas diagnostic of deteriorating transformer condition
    • Expedites operational decisions without needing to go to site for manual oil sampling
    • Issues can be detected in their infancy, avoiding unexpected failures and facilitating planned outages
    • Anchors condition based maintenance and asset replacement strategies on hard data
    • No need for consumables or frequent recalibration to operate at optimum performance
    • New “Rapid Mode” provides near real-time insight on fast developing faults
    • Enhanced computing power and scalable I/Os for a flexible transformer monitoring solution
    • Compatible with mineral insulating oils and newer ester based fluids (natural and synthetic)

     

    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 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.
