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

Innovative two enclosure design enables adjacent or separated installation arrangements to better accommodate varied site conditions

Communication Options – Extensive local and remote communications options
