Insulation for high voltage (HV) application such as cable subjected to several types of degradation. These degradation can lead to premature breakdown and when its happen cost to replace or repair equipment will be higher. Many research was done to improve the insulation properties and currently nanocomposite material get serious attention due to their abilities to enhance electrical performance by addition of nanofiller into the based material. In this paper, water absorption of Linear-Low-Density-Polyethyelene (LLDPE) with different amount of nanofiller composition is studied. This study is necessary to be conducted since polymer based material is the most common insulation material used in HV cable. The HV cable normally will be continuously exposed in uncontrolled environment. Because of this, the cable will exposed to watery condition and it is crucially needed for the insulation to remain dry to the cable performance. Three types of nanofillers at different weight percentage (%wt) added into LLDPE, was used in this study are: Silicon dioxide (SiO 2), Titanium dioxide (TiO 2) and Monmorillonite (MMT). Percentage absorption of water was measured according to BS 6470 until the samples reaches saturation level. Experimental result demonstrate that SiO 2 absorb less water than other filler while, the MMT has hydrophilic properties which it absorb more water compare to another sample. By used appropriate composition and type of nanofiller, a good insulator that are resistant to environmental influence can be produced

The properties of insulation have been improved by many research and the ability of nanocomposite material that composes the characteristic of improving electrical performance due to the addition of nanofiller into the based material gets serious attention. Polarization and Depolarization Current (PDC) measurement that has the ability to assess the condition of HV insulations with the initial periods after a DC step voltage application was favoured compared to other non-destructive monitoring techniques. This paper presents the works on moisture absorption in LLDPE-NR nanocomposite with different amount and percentage of nanofillers. The study of PDC level of the LLDPE-NR compound, filled with different amount of SiO2, TiO2 and MMT nanofiller using Polarization and Depolarization Current (PDC) measurement technique is the main objective of this research. These results show that sample A1 has the lowest polarization current value and sample B5 has the lowest depolarization current value.

“…Among the non-destructive monitoring techniques, Polarization and Depolarization Current (PDC) measurement is gaining popular due to its ability to assess the conductivity of HV insulations within the initial periods after a DC steps voltage application. Polarization and Depolarization Current test had been applied to LLDPE-NR Nanocomposite on normal condition without any defect [5][6][7][8]. This technique is very useful to estimate conductivity and moisture contents of the insulations.…”

Polymeric nanocomposites are widely used for high voltage outdoor insulating application due to their good electrical performance. Recently, SiO2, TiO2 and MMT nanofillers are being used as filler because there are listed as main nanofiller commonly used in electrical engineering. Natural rubber (NR) was used because the nature of the interphase is found to affect viscoelasticity and it develops several interphases with the Linear Low-Density Polyethylene (LLDPE) matrix. One of the problems associated with outdoor polymeric insulators is tracking of the surface which can directly influence the reliability of the insulator. This paper presents the outcome of an experimental study to determine the conductivity level of the LLDPE-NR compound, filled with different amount of SiO2, TiO2 and MMT nanofiller using Polarization and Depolarization Current (PDC) measurement technique. LLDPE and NR with the ratio composition of 80:20 were selected as a base polymer. Results show that different compositions as well as the surface physical conditions affect the PDC measurement results.
