To monitor PD activity, coupling capacitors (CC) are widely used as sensors for online PD detection, as they can effectively capture PD pulses in high-voltage (HV) rotating machines. The primary objective of this research is to measure and analyze PD signals using a CC sensor for HV rotating machines under varying input voltages and frequencies, following the guidelines of the IEC 60270 standard and utilizing the MPD 600 device. The experimental setup includes performing insulation resistance (IR) testing, PD calibration, and PD measurement. Additionally, this paper provides a detailed study of PD signal characteristics, specifically focusing on phase-resolved partial discharge (PRPD) patterns, to understand the behavior of PD in HV rotating machines, enhancing fault diagnosis and preventive maintenance strategies.</span></span> Partial Discharge (PD), Coupling Capacitor (CC), High Voltage Rotating Machine (HVRM), Phase Resolve Partial Discharge (PRPD). 233 249 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-5547-1&slc_lang=en&sid=1 Ahmad Syukri Abd Rahman ahmadsyukri@studentmail.unimap.edu.my 1800319475328460016556 1800319475328460016556 No MHH Condition Monitoring Sdn Bhd, No.8, Tingkat 1, Jalan Sumazau 1J/KU5, Bandar Bukit Raja, 41050 Klang, Selangor, Malaysia.
