SmartDGA Gauge is the newest addition to LumaSense's line of dissolved gas analysis (DGA) solutions to accurately identify and mitigate faults, supporting e. g. continuous online condition monitoring for load tap changers.

Online PR News – 29-March-2012 – Santa Clara, CA – SmartDGA™ platform employs infrared gas-sensing technology, features unique hardware design that dramatically reduces installation time, costs significantly less than traditional DGA systems

LumaSense Technologies, Inc. introduced a new category of dissolved-gas analysis (DGA) monitors that allow electric utilities to more effectively reduce outages caused by faulty load tap changers (LTC’s) and transformers. At a cost significantly less expensive than comparable dissolved gas analysis monitors and a unique hardware design that drastically cuts down installation time, the LumaSense SmartDGA™ platform ( http://www.lumasenseinc.com/EN/products/gas-monitoring/dga-for-transformers/smartdga.html ) can help utilities achieve widespread condition monitoring across generation, transmission and distribution assets.

The SmartDGA Gauge provides valuable information about load tap changers on a real-time basis which is very important if we’re serious about bringing concepts like Smart Grid to reality.

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, LumaSense's new dissolved gas analysis monitors (DGA) 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 new line, the SmartDGA Gauge, will be the industry’s first dedicated online gas monitor for LTCs (Load Tap Changers). "We believe Smart Grid begins with an optimized supply network in the utility grid. This means having reliable assets in the generation, transmission and distribution networks globally," said Vivek Joshi, LumaSense CEO. "The SmartDGA Gauge provides valuable information about load tap changers on a real-time basis, which is very important if we’re serious about bringing concepts like Smart Grid to reality."

SmartDGA Gauge is the newest addition to LumaSense's line of solutions designed to provide utilities more information about how their transformers are functioning to accurately identify and mitigate faults supporting e. g. continuous online condition monitoring for load tap changers (LTC), ability to find coking and other faults, hassle-free installation, no routine maintenance or calibration, no requirement for carrier gas, ability to monitor ethylene and acetylene to assess LTC health, vertical or horizontal mounting and installation on single valve, dual valve or inline with filtration system.

The SmartDGA platform ( http://www.smartdga.com ) 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 Gauge requires no carrier gas, no frequent calibrations and can be easily retrofitted to LTC’s to provide asset condition status.

LumaSense also provides a range of fiber optic temperature sensors (LumaSMART™ and LumaSHIELD™) used to monitor winding hot spots, and continuous thermal imaging systems (ThermalSpection™) that remotely monitor substations. Utilities can now deploy these complementary technologies from LumaSense to predict and correct faults as a part of utility Condition Based Maintenance programs.
