The centerpiece of all our optical systems in the field of gas-insulated switchgear is the light sensor, which allows a direct view into the GIS / GIL. It can be taken into account cost-effectively in the planning phase and is compatible with both systems - arc detection and optical partial discharge monitoring.

With the light sensor installed, both the OTEM and LiBo systems can be cost-effectively retrofitted to your switchgear at a later stage. The ability to carry out mobile testing is ensured by the installed light sensor. This allows the optical systems to be connected to the light sensors at any time in the event of PD anomalies, cyclical maintenance, soak tests or high voltage tests.

For equipment that is not yet equipped with light sensors, it is possible to retrofit these in the course of a system overhaul. However, it is recommended to consider the light sensors already in the planning phase in order to avoid work on the GIS / GIL during operation.
