GE is a leader in transformer condition monitoring, with a strong focus on Dissolved Gas Analysis (DGA). Understanding the health of transformers is critical for the reliability of electrical networks, and GE’s Kelman DGA 900 MULTITRANS offers advanced on-line monitoring solutions that are essential for modern asset management programs. By providing comprehensive and real-time insights into transformer conditions, this technology not only helps prevent costly failures but also optimizes asset performance, ensuring that capabilities are fully maximized. GE continues to drive innovation in DGA, supporting the effective and efficient management of critical infrastructure.

The Kelman DGA 900 TAPTRANS is the next generation 9-gas on-line transformer multi gas DGA (Diagnostic Gas Analyzer) monitor. Built from the DGA 900 platform, the TAPTRANS extends the capability beyond measuring a single transformer main oil tank.
The Kelman DGA 900 TAPTRANS is a patented designed specifically for transformers with an On-Load Tap Changer (OLTC), which is recognised as one of the most important parts of the transformer and which accounts, according to statistics, for a large portion of unplanned outages. It offers discrete multigas on-line DGA and moisture monitoring, separating the main and selector tanks from the diverter tank to avoid any risk of contamination. Utilizing photo-acoustic spectroscopy (PAS) measurement technology, well suited to field application, it provides laboratory challenging levels of precision and repeatability.
The Kelman DGA 900 MULTITRANS is the next generation 9-gas on-line transformer multi gas DGA (Diagnostic Gas Analyzer) monitor. Built from the DGA 900 platform, the Multitrans extends the capability beyond measuring a single transformer main oil tank. With only one sensor you may measure online the dissolved gases of your whole transformer bank (three individual main tanks).
Using our 4th generation of advanced photo-acoustic detection technology, the DGA 900 MULTITRANS 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.
