The most critical parameter to monitor on a transformer is the temperature. Transformer life is directly related to the life of the insulating paper inside. The life of the insulating paper is directly related to temperature it is exposed to. The highest temperature on the windings is the Winding Hot Spot (WHS), where the insulating paper is most likely to break down first. Conventional methods only simulate or calculate this temperature, but not directly measure it.
The only way to know exactly the temperature at the WHS
The LumaSMART is designed to provide real time transformer temperatures that can be used for protection and control at a cost effective price. Transformers are critical assets that often take the brunt of an overload condition and are the most likely to be damaged without proper control and protection. The drift-free, calibration-free nature inherent in the patented Fluoroptic® technology makes the LumaSMART ideally suited for use in transformers as a reliable and cost-effective means of protection for these valuable assets.
LumaSense's Dip-Tip Rugged Probes™ are considered the industry standard and the highest quality, most reliable and robust winding temperature probes in the world, with >99% installation success. Based on the patented Fluoroptic measurement principle for its reliability, Dip-Tip Rugged probes are PFA Teflon-jacketed featuring five-layer protection in their fibre optic encapsulation, including Kevlar for crush protection. They are specially designed to withstand harsh environments without deteriorating physically or affecting the accuracy of the temperature measurement. Dip-Tip Rugged probes are calibration-free and remain accurate for the life of the transformer.
Smart Grid ready LumaSMART HV Power Transformer Hot Spots Temperature Monitoring
The Lumashield Gallium Arsenide (GaAs)-based product line is the best alternative technology in the market to measure transformer temperature. It is best fit for utility companies that want to measure hot spot winding for smaller transformer of less than 20MVA and distribution transformers that have a smaller asset management budget.
