| Summary: | Polymeric nanocomposites have gained importance in the material properties to provide enhanced performances such as electrical and mechanical properties. One of the targets in this field is to obtain new materials with improved dielectric properties for High Voltage (HV) insulation application. In general, the good insulator must have low conductivity level. This paper presents the outcome of an experimental study to find the conductivity level of LLDPE-Natural Rubber (NR) compound filled with different amount of nanoparticles of SiO2 and TiO2 by using Polarization and Depolarization Current (PDC) measurement technique. PDC measurement is an efficient and effective insulator diagnostic technique based on time domain measurement to monitor the dielectric behaviour. The experiment was conducted to find PDC pattern and conductivity variations of each new sample. The results show that the addition of SiO2 filler exhibited in less conductivity compared to TiO2 filler with certain percentage. LLDPE-NR/ SiO2 can be a good insulator compared with LLDPE-NR/ TiO2. |
