Research on The Remoter Monitoring and Control System of Transformer Winding Temperature Based on Optical Fiber Networked Sensor

A standard generic network interface was designed for an optical fiber sensor based on CANbus. An advanced method of temperature measurement was adopted for the winding temperature in large power transformers by the networked sensor. It offers a lot of interesting features such as plug & play in the network. The on line supervision system of the winding temperature in large power transformer was founded. The design of the mesosphere software using WebSnap was showed. It is implement remote monitoring function based on B/S model. Its operations have proven that the network sensor solve the problems of high voltage and strong disturbance in site and realizes temperature on-line supervisory for large-scale transformer windings. It is easy to send the field data to the network at hand. All its advantages show the promising future of the application
