500kV发电机单相变压器直流偏磁噪声试验

500kV Single Phase Generator Transformer DC Bias Noise Level Test

本文中作者对500k V发电机变压器在空载和负载下直流偏磁噪声进行了试验研究,并对不同状态下的时域和频域波形进行了奇异谱和功率谱分析。

The DC bias noise level of 500kV generator transformer under no-load and load is researched by the authors in this paper. The time-domain and frequency-do- main waveforms of different states by singular spectrum and power spectrum are ana- lyzed.
