Surface flashover is a devastating electronic avalanche along the gas–solid interface when
a high electric field is applied, which is a potential issue that threatens the safe operations of …

The location mismatch of power production and consumption makes the large capacity
energy transmission rather necessary. Overhead transmission line has always been the …

This paper reports an unpredictable insulation surface flashover phenomenon triggered by
surface charge clusters under DC electric field, which is experimentally revealed by a donut …

This report intends to reveal the role of electron migration and its effects in triggering direct
current (DC) surface flashover under temperature gradient conditions when using epoxy …

Surface charges have the effect of changing the electric field over spacers in compressed
gases, which may affect the stable operation of gas insulated equipment and could possibly …

Surface charge accumulation on the spacers is one of the key issues restraining the
development of HVDC GIS/GIL. The precise measurement of surface charge properties …

The accumulated charges on the insulator surface become a key factor to incur surface
flashover. The charge accumulation process is closely related to the surface condition. This …

Polymeric composite insulators consisting of core fiber reinforced polymer insulators
covered with polydimethylsiloxane (PDMS) housing are now replacing conventional ceramic …

Surface charge decay kinetics on corona-charged polymeric insulators were studied. In the
experiment, the sample surface exposed to corona was kept open to ambient air whereas …

Surface charge accumulation on insulators becomes an important bottleneck to restrain the
development of a DC energy transmission system. This study investigates the effects of …
