SmartDGA for Transformers
LumaSense Technologies is a world leader in sensing solutions, with over 50 years of temperature and gas sensing expertise in various industries. We’ve brought together our experience with over 5,000 transformer temperature sensing installations and over 400,000 NDIR instruments.
Over time, as thermal and electrical stresses accumulate, the transformer’s insulating materials start to breakdown and release different gases. Detect these gases in transformer insulating oil by using sensitive and reliable Dissolved Gas Analysis (DGA) techniques to determine the type of impending or occurring fault.
LumaSense offers a cost-effective online monitoring solution for LTCs and transformers based on proven non-dispersive infrared (NDIR) technology. With online monitoring, utilities can automate the manual oil sample process to capture data every day and implement condition based maintenance (CBM) strategies to reduce the number and frequency of maintenance cycles.
The SmartDGA instruments works in cycles (as often as every 4 hours) to obtain a sample of oil, detect concentrations (in PPM) of key gases, and record the values. The robust DGA Viewer software includes industry recommended tools such as rates, ratios, Duval Triangle for detecting fault types, including Partial Discharge (PD), Discharges of Low Energy (D1), Discharges of High Energy (D2), Thermal Fault (T1), Thermal Fault (T2), and Thermal Fault (T3).
Each solution includes the SmartDGA instrument, the SmartDGA EZHub unit, connection cable, and mounting hardware. Improve safety and reliability by implementing the lowest total cost of ownership solution in the industry with no consumables, carrier gases, or scheduled calibrations.

SmartDGA® for Safer and More Efficient Asset Utilization
SmartDGA® addresses these major challenges:
Cost of Ownership
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. SmartDGA® is affordable - sometimes half the cost of other monitors with no consumables or scheduled maintenance.
Our SmartDGA® solution offers flexibility and the ability to accurately identify and mitigate faults by using IEEE and industry recommended guidelines for automated fault identification and alert.
Most monitoring technologies are cumbersome to install, maintain, and service, leading to a poor overall user experience. SmartDGA offers versatile monitoring configurations, including optional inline mounting.
Measurement up to 9 Gases
