Multiple Gas Transformer on line DGA Kelman DGA 900

Description

Multiple Gas Transformer on line DGA Kelman DGA 900

Kelman DGA 900 On-line Dissolved gas analysers  for power transformers , Generators transformers and reactors  monitoring all 9 fault gases plus moisture. The Kelman DGA 900 features an innovative two enclosure design, local/remote HMI and expandable analog/digital I/Os.DGA 900 is an 9-gas on-line transformer Dissolved gas analyser 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

DGA900 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

DGA900 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
• 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)
• 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
