Experimental Study on Transformer under DC Bias

Abstract:

As the voltage level to improve, DC bias problem of power transformers increasingly prominent. When the DC current affects the transformer, transformer laminated core magnetization characteristics inside will be affected by magnetic saturation increased. Aiming at this problem, the model of the load side and a smart experimental platform are established, for the measurement of related data such as the excitation current under DC bias. Based on MATLAB software, analysis summarized the laws of physics, to provide a reference for theoretical research.
