| description | The paper is devoted to partial discharge measurement
and analysis in switchgear bushings. PD bushing
structure analysis is described to assess possible
defect sources in bushings. An experimental 10 kV
bushing sample with the natural defect is obtained
from the bushings’ manufacturer. It is tested using
the PD measurement technique. Test results showed
significant PD intensity at voltages from 12 kV and
higher. We have an assumption that a part of registered
discharges occurred in the air close to the high voltage
electrode sharp edges. To check this assumption we
grind them off and repeated the test. The second
test does not show considerable PD characteristics
change. Therefore, we assume that the bushing sample
has an inner defect because the bushing’s surface is
not contaminated to generate surficial discharges.
The bushing is researched by a destroying method
for defect localization. However, inside the bushing,
possible defect locations are not found. It might be
connected with the fact that the defect could not be
found visually at the test time or the defect is located
in the gasket between the high voltage electrode
and insulator’s body. Besides, there are determined
features of phase-resolved partial discharge patterns in
switchgear bushings. |
