Reliability and safety the most important attributes in generator and transformer technology. The Optocon AG developed for this purpose the fibre optic thermometer FOTEMPTrafo, that effectively support in these areas. To ensure a constant and guaranteed operational safety, the temperatures are monitored at critical points in transformers and generators permanently.

To ensure operational safety in power plants and grids, Optocon has introduced a variety of fibre optic temperature measuring devices and temperature sensors for temperature monitoring in oil-filled power transformers. With a high system accuracy of +/-0,2°C and fast sampling rates per channel, the FOTEMPTrafo temperature signal conditioner offers reliable real-time temperature results.
