Transformer Bushing Online Monitoring System

The main transformer bushing is one of the critical components of power transformers, with dielectric loss and equivalent capacitance parameters serving as important indicators for assessing the insulation condition of capacitive equipment. By conducting real-time online monitoring of the leakage current, equivalent capacitance, and dielectric loss of capacitive bushing equipment, the insulation status of high-voltage electrical equipment can be continuously tracked. Additionally, analyzing the monitored data enables timely detection of potential faults in main transformer bushings and provides essential data support for condition-based maintenance. This ensures the safe, reliable, stable, and economical operation of the power system while delivering dependable insulation information and scientific maintenance guidance to operation and maintenance personnel. Consequently, it reduces the occurrence of accidents, extends maintenance intervals, minimizes the frequency and duration of outage-based repairs, and enhances equipment utilization and overall economic efficiency.
