| Abstract: | The transformer's noise shows the characteristics of low-frequency,low distance-decay and large sphere of influence.This paper briefly analyses the measured noise data radiated from transformers which locate in a Shanghai 220kV open-air substation,discusses the intensity and frequency characteristics of transformer's noise,and explores the propagation attenuation characteristics of transformer's noise within the scope of different distance. |
