“…One of the important property in High Voltage insulation is breakdown strength and any improvement thereof can lead to significant advantages such as decrease of size and reduction of cost. Polymers' characteristics such as high protection to resist dielectric charge, thermal conductivity, chemical cavities and tree growth, accord them an advantage as insulation materials [2]. In electrical applications, many type of polymers such as polypropylene, polyethylene, polystyrene, poly (vinyl chloride) and synthetic rubber can be used as insulation [2].…”

“…Nanocomposites can be defined as combination of polymers and nanofillers that contain at least one dimension less than 100 nm in size. Desired dielectric properties can be accomplished by combining polymers and nanofillers [2]. The accomplishment of nanocomposites in relation to partial discharge (PD) and AC breakdown test is exceptional but the present of nanofillers could lead to the formation of agglomeration of the fillers which may abolish the true effectiveness of the composites [3].…”

In high voltage systems, it is important to have good insulation systems in order to transfer power over a long distance. The use of polymer nanocomposites could make differences in insulation system. However, the presence of water in nanocomposites could negatively affect the performance of nanocomposites as it is found that nanocomposites can absorb more water than unfilled polymers. This study investigated the AC breakdown strength of polypropylene (PP) as polymers blends with 1 wt%, 2 wt% and 5 wt% of barium titanate (BaTiO3) nanofiller and analyzed the effect of water absorption on breakdown strength of polypropylene added with different amount of barium titanate nanofiller. All the samples of nanocomposites were then subjected to water absorption process for certain periods which are 0 days, 10 days, and 20 days to evaluate how much water can be absorbed by the samples and its effect on breakdown strength of nanocomposites. While AC breakdown test was conducted according to standard of American Society for Testing ance Material (ASTM) D149 to correlate the effect of water absorption with the breakdown strength of nanocomposites containing barium titanate.
