System overview
System overview
The reliability and service life of oil-immersed power transformer is an important guarantee for the safe, reliable and economical operation of power system. As the main node of power system, it has wide coverage as well as high value. When the fault occurs, it has a wide range of impact with great harm and serious economic losses. The traditional "thermal simulation measurement method" and "indirect calculation measurement method" can not meet the actual need for transformer winding temperature measurement in real-time, accuracy and other aspectes. The use of gallium arsenide fiber optic temperature sensing technology "direct measurement method" is an inevitable choice.
