| description | The article investigates partial discharges (PD) as a mechanism
of insulation destruction. Some of the known mathematical
models of insulation aging take into account the effect of partial discharges. These models are based on the dependence of partial
discharges power on voltage, so this dependence is investigated
in the article. Experimental studies of the dependence of the
characteristics of partial discharges are presented. As a source
of an increased level of partial discharges, a defect is used in
the termination area of the 10 kV cable with XLPE insulation.
The voltage range of experiments is from 8 to 15 kV. The results
show the presence of a dangerous defect in the cable. Partial
discharges at 8 kV are insignificant. However, 10 kV leads to the
appearance of significant partial discharges. PD at 15 kV have the
most devastating effect on insulation. The results are processed
to assess the dependence of PD power on voltage. The resulting
dependence is consistent with existing research results. However,
the obtained characteristics may change over time due to the
growth of the defect. |
