| Abstract |
Electrical tree phenomenon commonly occurred in solid insulator material resulting
from the inconsistency of stresses during the manufacturing process. The treeing phenomenon will
degrade the characteristic of insulator and may lead to breakdown. The use of filler in the
manufacturing process in order to enhancing the insulation property is a popular approach. This
paper presents the use of coconut shell powder (CSP) filler in epoxy resin for inhibition of electrical
tree growth. The particle sizes of CSP varied from 62, 75 and 125 µm. The CSP is filled with the
ratio of 0.1, 0.2, 0.4, 0.6, 0.8, 1.0, 2.0 and 3.0% by weight. We aim to observe the effects of varying
the combination of CSP particle sizes and the ratio of epoxy resin for an inhibition of electrical tree
growth. The electrical tree was tested by applying AC voltage of 15kV to the test sample and
conducted for 360 minutes in this experiment. When the epoxy resin using CSP filler of 1% by
weight is fixed for the particle size of 62, 75 and 125 µm, electrical tree length is at 1.24mm,
1.382 mm and 1.78 mm respectively. Whereas, when the particle size of CSP at 62 µm is fixed, a
tree length is 1.98 mm and 1.24 mm for the ratio of 0.1 and 1% by weight respectively. Our study
demonstrates that the epoxy resin using CSP filler at a ratio of 0.1% by weight can shorten length of
electrical tree when compared with a ratio of 1.0% by weight. The electrical tree length was
affected through the changes of permittivity by addition of CSP compound. |
