| Summary: | The article describes the study of the characteristics of partial
discharges (PD) in various types of artificial defects in cable
lines. A total of 13 types of insulation defects are considered.
The PD measurements are carried out using a high AC
voltage source and a commercial PD recorder. For each type
of defect, diagrams of the amplitude-phase distribution of
PD (APDPD), the average value of the apparent discharge,
and the PD intensity are obtained. The results of the study
show that most of the defects of insulators of overhead power
lines have a relatively high intensity of partial discharges with
a small average apparent charge. In the samples of cable
lines, relatively high values of intensity and average apparent
discharge are recorded in the presence of a defect in the end
seal and a defect in the ground electrode in the form of a
needle. The results obtained can be used in the development
of devices for detecting defects, as well as for expanding the
base of diagrams (APDPD). |
