Manufacturer of fluorescent fiber precise temperature measurement device for oil immersed transformer winding temperature measurement

Fluorescent fiber optic measurement of hot spot winding temperature in oil immersed transformers

Under overload conditions, transformers are most susceptible to damage. Therefore, monitoring the hot spots in transformer windings is crucial as it can protect your transformer from damage and excessive use.

The lifespan of transformers is directly related to the lifespan of internal insulation paper. The lifespan of insulation paper is directly affected by high temperatures, and the highest temperature on the winding is the hot spot of the winding, which is the location where the insulation paper will first deteriorate. The conventional temperature measurement method simulates or indirectly calculates this temperature value, which cannot accurately measure the actual temperature. The only effective way to know the actual temperature value is through real-time measurement using optical fibers.

The precise fiber optic temperature measurement device independently developed by FJINNO manufacturer can quickly detect and provide feedback on hot spot situations. It triggers alarms and relays to protect the normal life of oil immersed transformers.

This device is designed specifically for power applications and is very suitable for measuring the temperature of hot spots in transformer windings. It is a new type of transformer internal temperature monitoring device that can directly, real-time, and accurately measure the temperature of hot spots such as windings, and can achieve comprehensive monitoring of the transformer's internal environment. In addition to having a wide temperature measurement range and accurate and reliable temperature measurement performance, it also has excellent anti EMI/RFI (electromagnetic interference/radio frequency interference) characteristics, high-voltage insulation, and anti-interference performance.

Real time and accurate monitoring of "hot spot" temperature during dynamic load operation can be achieved.

Solved the problems of low safety, poor measurement accuracy, and temperature measurement failure using traditional electrical temperature measuring instruments in electromagnetic environments.
