OPT100
Optimus™ maintenance-free multi-gas DGA monitor for power transformers
An online dissolved gas analysis (DGA) monitor for critical power transformers. It samples the oil using vacuum gas extraction and measures all seven fault gases plus moisture with reference IR sensing and autocalibration, with no carrier gases or consumables. Total gas pressure measurement detects air leaks in sealed transformers, and the integrated web interface removes the need for extra software.
