| Abstract |
This research presents a technique for the enhanced detection of Partial Discharge(PD) signals using a High-Frequency Current Transformer(HFCT). The peak of the PD signal, as detected by the HFCT, is identified within an amplifier composed of R-C parallel circuits. To streamline the peak data collection and identification process executed by the MCU, the capacitance of the capacitors and the amplification ratio of the amplifier were modulated. The findings confirm that an increase in capacitor capacitance extends the charging and discharging time, consequently altering the average voltage of the peak detection signal. Furthermore, an increase in both the amplification ratio and the capacitor capacitance leads to an augmented overall average voltage of the peak detection signal, thus facilitating identification within the MCU. This study aims at the improvement of PD signal detection techniques using HFCT, positing the potential to enhance the efficiency of partial discharge detection and management through actual performance improvement. Such outcomes are anticipated to deepen our understanding of PD detection technology and contribute to expanding the potential applications of this technology. |
