Distributed Temperature Sensor
Sumitomo Electric not only manufactures cables and overhead conductors, but with the operation and maintenance of these products in mind, it has also independently developed a product portfolio of distributed temperature sensors, which monitor conductor temperature.
As a conductor manufacturer, Sumitomo Electric has gained a thorough knowledge of conductors. Integrating its product system technology, the Company offer the added-value of new conductor systems, including temperature abnormality monitoring and dynamic cable rating.
One of Sumitomo Electric’s biggest strengths is its capability of the in-house manufacturing of temperature monitors, allowing it to customize the product to fit customer needs in various ways, including measurement accuracy and measurement distance. As this product can be used not only for multi-mode fiber, but also for single mode fiber, it easily retrofits existing transmission lines with optical fiber to measure the temperature distribution of conductors.
This wireless temperature sensor for overhead conductors is unique in the world. With respect to overhead conductor temperature prediction based on just conducted electricity and weather conditions, it allows us to take direct measurements of conductor temperature for more accurate temperature measurements and through dynamic rating, which demonstrates even higher usefulness, we are able to enjoy many more benefits.
- Detection of conductor heat generated by such problems as an overload
- Significant increase in power transmission capacity through dynamic rating
- Measurement of t Abnormal temperature in such equipment as transformers
