“…The difference in the dielectric breakdown process between positive and negative impulse voltage can not be described only by using the applied electric field distribution in the gap. The effects of the space charge generated at the local electrical discharge must be included in the analysis [11]. Space charge will be generated around the local electric discharge and adjacent to the rod electrode, for the local electrode discharge -rod geometry, because the highest electric field is located both adjacent to the local electric discharge electrode and the grounded rod.…”

The characteristics of impulse breakdown voltages and the influence of the position of third electrode in air gap are investigated experimentally to study the parameters influencing the breakdown voltage in the presence of metallic objects around the high voltage power apparatus with air insulation. Experimental results show that the factors affecting the breakdown voltage are the shape and the size of the grounded electrode, the third metallic electrode location and the gap length. A comparison between negative and positive polarities of the applied voltages indicates an important influence of the polarity in the dielectric breakdown mechanism. The possible mechanism by which the local electric discharge initiates the main dielectric breakdown seems to be the high electric field around the local discharge channel and the streamers protruding from its surface.

“…Monte Carlo simulation and self-consistent particle simulation in SF 6 gas environment was carried out to study the fundamental discharge processes [20]. Lately, S. Baika et.al reported that the sensitivity of CNTs about dissociated species of SF 6 substantially increased by functionalizing with benzene [21].…”

The detection of dissociated SF 6 species, generated by partial discharge (PD), is of great importance because the dissociated compositions can alter inherent potential of SF 6 and pose safety risks to power systems. Here we report that the sensitivity of carbon nanotubes (CNTs) about dissociated species of SF 6 substantially increases by functionalizing with Tin oxide (SnO 2 ). SnO 2 /MWCNTs nanocomposites was prepared by a simple route that included in situ growth of SnO 2 on the surface of MWCNTs through hydrothermal method in this work and characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis techniques. The chemical sensors based on SnO 2 /MWCNTs nanocomposites exhibited good sensitivity in response to decomposition components at room temperature.The work provides an appropriate functionalization methodology to conduct the dissociated SF6 species monitoring.
