Research On Influence Of Environment To Dielectric Loss On-line Monitoring Of Capacitive Equipment

The dielectric loss on-line monitoring of capacitive equipment changes along with the climate, for the comparable of dielectric loss of different climate, we get the signal by capacitive divider in the manual environment room to study their relation. To monitor the climate condition, we design the manual environment room which can adjust the temperature, humidity and the air pressure. We also design the on-line monitor system of the manual environment room and the dielectric loss base on LabVIEW, and get the curve relation of the dielectric loss of a 110kV capacitive bushing and the climate condition by experimention.
