- The temperature sensor element is a passive optical fibre that is integrated into the core of OPPC (optical phase conductor). This enables a wide range of sensor applications.
- Via joints and high-voltage fibre optic uncoupling devices, the fibre is linked to an EN.SURE evaluation unit where the distributed temperature profile is recorded and can be further processed.
- Alternatively, the fibre optic cable can be helically applied on phase conductors. A specially designed spinning machine is used to wrap the cable under controlled conditions.
One example how to apply the external sensor cable can be found here:
