Kelman DGA 900
|
|
|
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.
