Intelligent On-line Monitoring Technology for Capacitance and Dielectric Loss of Electrical Equipment

摘要

In order to ensure the safe operation of capacitive equipment in substations, the on-line monitoring technology of capacitance and dielectric loss is implemented. In this paper, the phase comparison method and FFT analysis are used to obtain the insulation parameters such as capacitance and dielectric. Data are uploaded to the station terminal integrated processing unit through the field bus, and the remote diagnosis center is uploaded through the IEC61850 mode for data presentation and analysis diagnosis. The insulation defects of electrical equipment are diagnosed at the scene, and major accidents are avoided in time.
