DTS( Distributed Temperature Monitoring Systems)

A continuous and cost-effective monitoring solution of the electric power transmission and distribution grid is the key factor for a successful Smart Grid implementation.

Based upon raising load demands, Utilities need to be able to maximize the performance of the power cable systems safely and efficiently. Then, it is critical for the operators to understand what the thermal behaviours of the cable system and its environment are.

During high-load and emergency conditions, it must be ensured that maximum emergency temperatures are not exceeded.

LIOS EN.SURE is based on state of the art distributed temperature sensing (DTS) monitoring systems customised for the electrical T&D industry. One single EN.SURE evaluation unit provides fast temperature sensing profiles with high spatial resolution along the optical fibres route with monitoring ranges up to 40km per channel.

• Highly reliable industrial design with key components approved by the telecom industry (tested according to Telecordia standard GR-468, with media lifetime >25 years)
• Signal processing based on patented Raman OFDR-Technology (Optical Frequency Domain Reflectometry)
• Superior hotspot detection along the whole sensor cable length even at most remote distances based on the invariant OFDR spatial resolution.
• Flexible and direct connection to management systems such as SCADA and real time thermal rating (RTTR) software calculation engines based on IEC, AEIC and IEEE standards
• Up to 16 internal fibre optic channels - 1 EN.SURE DTS unit can cover the most complex power cable circuits
• Temperature resolution better than 1 °C
• Laser product class 1M according to DIN EN 60825-1 : 2007
• Maintenance free and simplified outdoor installation capability through higher allowed operating temperature range and fan-free DTS unit design - MTBF more than 30 years
• Impressive track record with more than 3500 permanent units installed worldwide
