This paper presents a measurement setup and network parameter-based analysis methodology for high-frequency transmission characteristics analysis between the primary and secondary sides of a PT (potential transformer). The raw data was extracted by measuring a scattering parameter (S-parameter) using a vector network analyzer. ABCD parameters were obtained using the measurement data to analyze the transmission characteristics of the transformer, and the source-transformer-load model was introduced to define the voltage and current gains considering the terminating impedance and input impedance applied to the transformer. Representative sine wave and square wave was applied to analyze the high-frequency transmission characteristics. In order to analyze the surge transmitted to the secondary system when applied to the actual system, the waveform of the IEC standard was generated and applied. When the load resistance is 1 MΩ, the voltage gain converted from the ideal turns ratio is applied to the input signal was confirmed that the maximum value of surge corresponding to about 1.9 times was formed.
