Smart-Grid-ready winding hotspot temp monitor

The LumaSMART winding hotspot temperature monitor builds on the ruggedness, reliability and stability pioneered by its predecessor products such as the WTS-22 and ThermAsset2. The LumaSMART is the industry’s first Smart-Grid-ready winding temperature hotspot monitor. For the operator, the touch screen display on the LumaSMART offers users easy-to-use trending tools, graphics, and alarm configurability necessary to customize the LumaSMART product to exactly fit their needs. In addition, enlarged on-board data storage allows 1 GB of historical data for analysis by the user. The LumaSMART allows a range of connectivity options, including RS232, RS485, TCP/IP and USB, along with numerous protocols, significantly simplifying integration with any SCADA or DCS package in substations. For the transformer manufacturer, it is compact, easy to install and configure. The LumaSMART is expandable to configurations allowing up to 16 measurement points and 16 programmable relays.

“The Winding Hot Spot Temperature is the single most critical parameter to monitor on your transformer. Using Luxtron’s patented Fluoroptic® Technology, LumaSMART offers the most flexible platform in the market to perform direct, real-time winding hot spot measurements,” comments Brett Sargent, Global Vice President of Sales for LumaSense Technologies. “The winding hot spot directly relates to transformer life, loading capacity of a transformer and predictive maintenance practices for the transformer. Beyond offering better accuracy, the LumaSMART’s communication and configuration features allow users to easily integrate this critical information into their automated data and control systems.” More information is available at
