Partial Discharge Online Monitoring System Introduction
          To meet the development requirements of nonstop maintenance for G1, transformers, switchgear, and power cables, this system utilizes IoT and intelligent sensor technologies to monitor power equipment under live conditions. Through smart sensor technologies—including Transient Earth Voltage (TEV), Acoustic Emission (AE & Ultrasonic), UltraHigh Frequency (UHF), and temperature monitoring—it enables intelligent detection of the operational status of transformers, GIS, switchgear, and power cables. By employing intelligent diagnostic algorithms and multidimensional comparative analysis, the system performs smart data analysis and equipment condition assessment, providing realtime operational insights, early defect detection, and evaluation of abnormal information and maintenance strategy recommendations. This supports maintenance personnel in decisionmaking, effectively preventing sudden power outages, fires, and personal or equipment hazards.

Partial Discharge Online Monitoring System Composition
