Design of Fiber Distributed Busway Temperature Monitoring System

Abstract:

The reliability of busway in high current state is closely related to its temperature. So effectively monitoring temperature is the key issue to ensure the busway work safely. Because of the constraints such as high voltage and strong electromagnetic fields, traditional temperature measurement system can not meet the requirements. A distributed busway temperature monitoring system is designed in this paper based on the temperature effect of fiber Raman scattering signal. Arithmetic average, wavelet noise reduction and low-pass filter combination of data processing is used to overcome the very low SNR. Experiments show that the system can measure the temperature of 1km busway effectively. Temperature resolution can achieve 3°C.
