Abstract

Electrical treeing behavior in low density polyethylene
and its nanocomposite filled with 1.0 wt% and 3.0 wt%
aluminum oxide nanoparticles was investigated by
means of a real-time microscope recording system and a
synchronized partial discharge measurement. For
preparing the nanocomposite, uncoated aluminum oxide
nanoparticles with 99.5% purity (Nanodur, CAS 1344-
28-1) were used. These were of almost spherical shape
with an average diameter of 45 nm. The test objects
were prepared in form of the wire-plane electrode
geometry [1]. The electrical treeing tests were carried
out by applying 50 Hz AC voltage at a ramping speed of
22 V/s. The obtained experimental results indicate that
the addition of the nanoparticles has a positive impact
on the resistance to electrical treeing. Both the scale and
the shape of the distribution of the treeing initiation
voltage improved. The magnitude of partial discharge
activity associated with the treeing in polyethylene
nanocomposites was also lower than in the reference
material.
