| Summary: | Composite polymeric insulators recently being widely
used to replace porcelain and glass in high voltage application.
While Polarization and Depolarization Current (PDC) is a nondestructive
measurement technique used to measure charging and
discharging current in time domain. This paper presents the
experimental and analysis result of PDC measurement technique for
new developed Nano-polymeric material samples. The new LLDPENR/
TiO2were developed by blending the polymer material of Linear
Low Density Polyethylene (LLDPE), natural rubber (NR) and filled
with nanoparticles of TiO2 as fillers. Several samples at different
percentage of filler added (1%, 3%, 5%, and 7%) was prepared and
tested with and without surface tracking defect. Surface tracking is
developed from surface discharged activity associated with the flow
of leakage current on insulator surface under wet and contaminated
conditions. Presence of impurities or contaminants on surface of the
insulator will affect the insulator conductivity. Aim of this study is to
see effectiveness of adding TiO2 as fillers improve polymer material
dielectric properties under surface tracking condition. Result of PDC
pattern and conductivity variation of each sample is analyzed using
LABVIEW and MATLAB to determine which sample has better
dielectric property. |
