SmartDGA® for Safer and More Efficient Asset Utilization

SmartDGA® addresses three major challenges:

  • Price: most DGA monitors are too expensive to support wide-scale deployment, thus limiting the ability to realize a Smart Grid and true condition-based maintenance.
  • Flexibility: online DGA systems lack flexibility and the ability to accurately identify and mitigate faults.
  • Ease-of-Use: most monitoring technologies are cumbersome to install, maintain and service, leading to a poor overall user experience.

The LumaSense Solution

LumaSense has developed a cost-effective online monitoring solution based on proven, state-of-the-art non-dispersive infrared (NDIR) technology.

This new suite of products is designed to allow customers to continuously monitor and control the condition of LTCs and transformers.
