Fiber optic temperature solutions for generator and transformer

DRESDEN, GERMANY: Due to the growing demand of energy, existing power plants and grids are stretched to their limits. To ensure operational safety, critical factors such as temperature has to be monitored in generators and transformers. High power generators are often filled with hydrogen in order to cool effectively. Besides the heavily contaminated electromagnetic environment the risk for explosions is high.

Optocon AG in Germany offers a variety of fiber optic temperature measuring devices, fiber optic temperature sensors and accessories for temperature monitoring in oil-filled power transformers. You can enjoy all the benefits of the fiber optic measurement principle. The outer jacket of the fiber optic temperature sensor is made out of PTFE, at the sensor tip a GaAs-crystal (gallium arsenide) is attached.

The GaAs based technology is ideal for smart grid temperature monitoring in transformers. The sensor is completely non-conductive. Optocon's fiber optic temperature sensors offer complete immunity to RFI and EMI emissions with high temperature operating capability, intrinsic safety, and non-invasive use. The fiber optic temperature sensors are also designed to withstand harsh and corrosive environments.

Starting at a light wave length of 850nm/Kelvin. The measurement device contains a light source and a device for spectral detection of the band gap. These guarantee fast, repeatable and reproducible measurements.
