PTI-P5 transformer bushing insulation online monitoring system mainly monitors the bushing dielectric loss, which can be more sensitive to find the insulation defects of capacitive equipment. Using online monitoring means, real-time monitoring under the operating state of equipment can not only find the insulation defects in time, but also achieve the purpose of replacing conventional preventive experiments. It provides a strong and reliable guarantee for the safe, reliable, stable and economic operation of the power system, and provides reliable equipment insulation information and scientific maintenance basis for the operation and maintenance personnel, so as to reduce the occurrence of accidents, extend the maintenance interval, reduce the number and time of power outage maintenance, and improve the utilization rate of equipment and the overall economic benefits.
