Analysis of Typical Partial Discharge Spectrum of High Voltage Parallel Reactor Discharge Defects

This paper examines methods for analyzing partial discharge spectra in high-voltage parallel reactor defects. Partial discharge, a critical precursor to insulation deterioration, necessitates accurate detection and analysis. Discharge models for sharp-edge, suspended particle, and bubble defects are established to analyze their mechanisms and characteristics. An experimental platform is developed to conduct discharge experiments, obtain waveform spectra, and analyze results. The findings highlight significant differences in the time-domain, phase distribution, and three-dimensional phase distribution of partial discharges across defect types, offering theoretical and practical support for fault diagnosis in high-voltage equipment.
