This paper reported the measurements and modeling of noise on the 22.9kV Medium-Voltage (MV) underground power distribution cable for Broadband Power Line Communication (BPLC). The proposed measurement system was composed of inductive coupler and Digital Phosphor Oscilloscope (DPO). The empirical noise data with the measurement system was obtained from thirty-two pad mounted transformers in the test field located in Choji area of Ansan city. After conducting analysis of noise characteristics in time and frequency domain, the noise model are presented. In order to analyze the noise in frequency domain, Power Spectral Density (PSD) was computed with empirical data using Welch’s method. The model of the power line noise at each frequency carried out using Cumulative Probability Distribution (CPD) of computed noise power. It compared with common Cumulative Distribution Function (CDF) of Nakagami-m distribution, Gaussian distribution, Gamma distribution. Below 20MHz frequency range, gamma distribution was fitted with the CPD. Nakagami-m distribution provides a good fitting to the noise CPD above 20MHz frequency range.
