Santa Clara, CA / Frankfurt/M, DE -- LumaSense Technologies provide a new category of dissolved-gas analysis (DGA) monitors that allow electric utilities as well as energy –intensive companies to more effectively reduce outages caused by faulty load tap changers (LTC’s) and transformers. At a cost significantly less expensive than comparable DGA monitors and a unique hardware design that drastically cuts down installation time, the LumaSense SmartDGA® platform can help utilities achieve widespread condition monitoring across generation, transmission and distribution assets.
Currently, less than 5 percent of transformers have condition-based online DGA monitoring systems, according to industry sources, and approximately 30 percent of all transformer failures in the United States are related to faulty LTCs.
Widespread condition monitoring was unattainable using traditional technologies, largely due to high costs and excessive installation time. Whereas other systems take days to install, a SmartDGA monitor can be installed in a matter of hours. Additionally, SmartDGA monitors will cost up to 50-percent less than other monitors. The first monitor in the line, the SmartDGA® Gauge, was be the industry’s first dedicated online gas monitor for LTCs.
The SmartDGA® platform uses non-dispersive infrared (NDIR) sensing technology. LumaSense has used NDIR technology in more than 400,000 instruments over the past 40 years. This extensive experience is coupled with a proprietary algorithm developed in accordance with recent utility standards to analyze and report LTC conditions. The SmartDGA® monitors require no carrier gas, no frequent calibrations and can be easily retrofitted to LTC’s to provide asset condition status.
