Partial discharges characteristics study in XLPE cable insulation with multiple defects
The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with one defect. On the basis of experimental stu...

| description | The paper simulates the electric field intensity picture
in the cable with one and several defects. Modeling
has shown that the presence of several closely spaced
defects does not lead to an increase in the electric field
intensity in comparison with one defect. On the basis
of experimental studies, an analysis of defects' number
influence on various parameters of partial discharges
(PD) is performed. Artificial defects are created in the
area of the XLPE-insulated cable termination. The
following parameters of PD are measured: the magnitude
of the apparent charge, the power (intensity) of partial
discharges, the phase-resolved partial discharge
(PRPD) patterns, the shape of PD signals. The analysis
shows an increase in the number of defects does not
affect the characteristics of partial discharges, despite the fact the defects are located in different sections
of the cable with distributed parameters. Thus, it can
be difficult to quantify defects during cable partial
discharge measurements. |
