Modelling on Tracking Test Condition of Polymer Nanocomposite using Finite Element Simulation
Abstract: Electrical tracking
is a formation process of a permanent conducting path across the insulating
material due to surface erosion under high voltage stress. The existing of leakage
current (LC) on the wet contaminated material surface causes the generation of
surface discharges that resulted in the material degradation. The effects of
electric field distribution and current density on LLDPE-Natural Rubber blends
material were investigated using finite element method (FEM) analysis. In this
paper, a variety of physical parameters particularly contaminant flow rate,
various applied voltages, material properties of permittivity and conductivity
were studied when nanofiller is added to LLDPE-Natural rubber blend. The
simulation works using FEM software of Quickfield was applied to the tracking
test condition of IEC 60587 standard.
The results show that the electric field distributions are critical on
the edges of contaminant solution path at higher voltage level. The current
density and electric field distribution is increase with higher applied
voltage. The polymer nanocomposite with 1-5 % of nanofiller exhibits a good
resistance to tracking and erosion test.
