Purpose/Aim
The detection of dissolved gas in transformer oil is of great significance to evaluate the health status of power transformers. Compared with the traditional chromatographic method, The optical method has the advantages of high safety, high detection limit, fast detection speed and no contact measurement. This paper simulates the process of detecting C2H2 concentration through Modulation Spectroscopy technique (WMS) to verify the feasibility.
Experimental/Modeling methods
The simulation model of the C2H2 detection system, consists of modules of pump light source, Lorentz linear function, photothermal process, interference, and interference demodulation. The 2f signal of the interference signal is extracted by lock-in amplifier.
Results/discussion
1. The peak value of the 2f signal has good linearity with C2H2 concentration.
2. The peak value of 2f signal reaches the maximum when the modulation coefficient is about 2.2.
Conclusions
WMS can be used for C2H2 concentration detection with the effect of optical interference effect and the appropriate modulation parameters are very important to provide a reference for the experimental detection.
