    This paper explains and demonstrates how to measured high-frequency signals in a distribution transformer. The high-frequency signals tend to suffer attenuation while propagating within a transformer to a detection device. In order to understand the propagation and attenuation characteristics of the high-frequency signals within the transformer, the highfrequency signal simulation in the transformer is essential. In this research, the reflection and the attenuation characteristics of high-frequency signals amplitudes as well as the frequency components of the high frequency while propagation through transformer winding and a core of transformer were examined both in the time domain and frequency domain measurement. The detail of high-frequency signals, including methods of detection device and material properties, are described in this paper. The infallibility of the experiment results was also evaluated.
