Distributed Temperature Sensing  
 

Kumwell Smart Distributed Temperature Sensing (K-DTS) is an advanced technology using fiber-optic monitoring systems and is designed specifically to enhance the safety of critical infrastructure and personnel. Kumwell uses the Raman ODTR technology with unique techniques that are designed for both Strokes and anti -Strokes. This approach results in outstanding system reliability, accurate measurements, and high performance. The position of the temperature reading is determined by measuring the arrival timing of the returning light pulse similar to a radar echo.

Application
 

Kumwell Smart Distributed Temperature Sensing System (K-DTS) is suitable for sites constantly operating or in a high-temperature area while in use, which requires safety from the fire risks such as cable trays, warehouses, manufacturing process, car parks, tunnels (road, rail, and metro), Large industrial facilities, Escalators, and more. This Smart Distributed Temperature Sensing System will make it possible to correct the situation that arises quickly. Also, the notification will be displayed through the monitor and LINE application when the temperature changes beyond the set value.

  Arc Protection System  
 

Electric Arcs can cause heavy damage and present a serious hazard to operating personal by switchgear. Several features may cause the arcing fault at switchgear such as the aging og insulation or operation mistake at switchgear. Kumwell Arc Protection Relay is the real-time distributed systems based on high-speed technology can rapid removal of arcing fault, reduce damage and improve personal safety. Kumwell Arc Protection Relay has been put in use in a number of key projects. Product tested according to standard IEC 60255-2009.
