The fiber optic temperature measurement device for oil immersed transformers is designed specifically for power applications and is an ideal choice for measuring the hot spot temperature of transformer windings. A new type of internal temperature monitoring device for transformers can directly, real-time, and accurately measure the temperature of hot spots such as windings, achieving comprehensive monitoring of the internal of transformers. In addition to having a wide temperature measurement range and accurate and reliable temperature measurement performance, it also has excellent resistance to EMI/RFI (electromagnetic interference/radio frequency interference), high-voltage insulation, and anti-interference properties.
Real time and accurate monitoring of “hot spot” temperatures during dynamic load operation can be achieved. Solved the problems of low safety, poor measurement accuracy, and failure in temperature measurement using traditional electrical thermometers in electromagnetic environments.
The fiber optic temperature measurement system for transformer winding includes
IF-TF series transformer winding fiber optic temperature measurement device
Internal fiber optic sensing probe
External fiber optic sensing probe
Penetrator/flange assembly
Optional Accessories
Control box
Integrated mouth protection box
Split mouth protective box
Protective cover (required for split type protective box)
Fixed components
Introduction to fiber optic temperature measurement probes
The fiber optic sensing probe is completely non-metallic and made of rare earth materials, which can be used safely in almost any environment. It is not affected by EMI, RF, MRI, and microwave interference, can withstand high voltage of 100KV, has small size, high temperature measurement accuracy, fast response speed, stable performance, no need for calibration, and directly contacts to measure hot spot temperature.
