“…The tracking analysis was carried out in accordance with IEC 60587 standard [24]. The scheme of the setup is shown in the figure 2 [25]. For tracking all the samples were fixed at an inclined plane of 45°having a distance of 50 mm between the electrodes.…”

Solid insulation materials are the backbone for all kinds of outdoor insulation applications. Environmental stresses degrade every outdoor insulation material with the passage of time. Internal partial discharges and external surface tracking are the two major factors governing the health of outdoor insulation. Best outdoor insulation is the one having lowest level of partial discharge and highest resistance to tracking. Improvement in tracking resistance of polymeric insulation materials has been a concern of many researchers. This study investigates the improvement in partial discharge and tracking resistance of LDPE under the effect of three different nano fillers including SiO 2 , TiO 2 , TiO 2 @SiO 2 . A very little has been reported on the effect of these nano fillers on the tracking performance of LDPE. TiO 2 @SiO 2 is a novel core-shell nano filler. No study has reported the effect of these core-shell nano fillers on the partial discharge and tracking performance of LDPE. It has been observed in this study that core-shell nano fillers are much more efficient in improving partial discharge and tracking resistance of solid insulation materials than ordinary nano fillers.

In last two decades a promising performance improvement in the electrical insulation materials has been reported by many researchers using different nano fillers (NFs). In recent years another type of NFs called core-shell type nano fillers have shown even more attention than ordinary NFs. The coreshell NFs are a combination of nano particle core coated with outer nano layer of different material. The core-shell NFs combine the beneficial properties of two material with in one NF. Recently a few studies have reported a considerable improvement in the dielectric properties of epoxy by utilising TiO 2 @SiO 2 core-shell NFs. The TiO 2 @SiO 2 particles have a core of TiO 2 coated with an out layer of SiO 2 at nano level. This study investigates the improvement in tracking performance of silicone rubber (SiR) using TiO 2 @SiO 2 core-shell nano particles which has not been reported previously. The tracking immunity of low (below 1%) and high (above 1%) filler concentrations of nano TiO 2 @SiO 2 incorporated into SiR was investigated according to IEC 60587. The results showed that an optimum percentage of 0.6 wt% of TiO 2 @SiO 2 imparts best immunity to silicone rubber against tracking.

“…Representative failure modes that have been reported in outdoor insulation applications are surface tracking and erosion. The occurrence of surface tracking, which is characterized by the formation of an irreversible carbonized conduction pathway [2,7], involves various development stages and factors, such as surface wetting, leakage current flow, dry-band zone formation, and local heat accumulation.

Effect of Filler Concentration on Tracking Resistance of ATH-Filled Silicone Rubber Nanocomposites

It is necessary for polymeric materials to have superior tracking resistance against various stress conditions for outdoor applications. In this study, the effect of nano-sized alumina tri-hydrate (ATH) particles on the tracking resistance of silicone rubber (SiR) is studied. Specimens with filler loadings of 1, 3, 5, 10, and 20 wt % are used for performance characterization. From the inclined plane test (IPT) results, apparent improvement in tracking resistance was achieved by mixing 3 wt % of nano-sized fillers, compared to unfilled specimens. ATH/SiR nanocomposites with 5 wt % loading showed comparable tracking performance to SiO2/SiR microcomposites with 20 wt % loading. For detailed analysis, measurements of surface contact angle (SCA) and surface leakage current, and thermo-gravimetric analysis (TGA) were performed. As the nano-ATH filler concentration increased, both thermal stability and leakage current characteristics were improved. Such results agreed with the tracking resistance performance by showing that thermal decomposition and surface charge transport is inhibited in ATH/SiR nanocomposites. Furthermore, performance improvement in nanocomposites was achieved, even at low filler loadings, compared to microcomposites. Meanwhile, the change in SCA was found to be rather limited, regardless of filler loading and filler size.
