Global energy demand of electricity has been increased, and it has been set to increase by 3 % per year in 10 years in Korea. As a result, monitoring the failure of power cables is concerned. Partial Discharges (PD) detection, one of the monitoring methods of power failure, has not yet been standardized in Korea. The measurement of the PD signal over the noise was performed. The Signal to Noise Ratio (S/N) of the PD needs to be considered because not only various noise sources exist around the monitoring site but a few hundred MHz to a few GHz PD signal is easy to be decayed as it is distant. The frequency ranges of the HFCT sensor that is able to compare PD signals quantitatively between 1 and 500 MHz were investigated between 1 and 50 MHz, which is the band used for current PD detecting methods. The simulated sample test showed a few favorable frequency ranges against noisy environment on the lower ranges of the HFCT sensor, and it tends to have higher S/N in upper frequency band among the detected PD signals.
