Transformer monitoring unit DGA 900

carbon monoxidenitrogen dioxidediagnostic

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. 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, highly scalable I/Os and integrated HMI combine to provide a powerful highly flexible transformer monitoring solution •Compatible with mineral insulating oils and newer ester based fluids (natural and synthetic) Features •DGA & Water – Nine gases (hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, nitrogen and oxygen) plus moisture •Inputs/Outputs for additional sensors including load and oil temperature •Full DGA results down to once per hour and new “Rapid Mode” for critical gases in just 30 minutes • Integrated 7” colour LCD screen for simplified local user interaction and visualisation of data
