Wetting characteristics of the hydrophobic material surface through condensation
High Voltage, 2023 Composite insulators are generally considered to have excellent anti‐pollution flashover performance, but recently there has been a flashover accident on the indoor clean insulator in China, which is suspected to be related to the wetting of insulators ...

High Voltage, EarlyView.ABSTRACT The breakdown characteristics of the novel eco‐friendly insulating gas CF3SO2F are fundamental to the design of gas‐insulated equipment. In this paper, the gas mixture parameters for CF3SO2F were optimised for different ambient temperatures in order to ascertain the insulation performance and liquefaction temperature constraints.

Micro Partial Discharge Characteristics of SF6 Under DC Voltage
High Voltage, EarlyView.ABSTRACT In gas‐insulated high‐voltage direct current (HVDC) devices, micro partial discharges (PD) caused by micro‐protrusions or surface roughness on conductors or enclosures may not cause immediate insulation system failure due to their weak discharge intensity.

Influence of fluorination time on surface flashover of epoxy in insulating gas [PDF]
, 2015 The accumulation of charges on polymeric insulation under high voltage DC stress is a major concern in the transmission system as its formation distorts the local electric field and has an adverse impact on the electrical performance.

High Voltage, EarlyView.ABSTRACT Film capacitors, essential for energy storage in power systems, benefit from reduced film thickness to increase capacitance and lower costs. While the inverse power law traditionally links higher electric strength with thinner films, its validity diminishes below a critical thickness.
