Journal ArticleDOI
Surface charge migration and dc surface flashover of surface-modified epoxy-based insulators
TL;DR: In this paper, the effect of direct fluorination on surface charge migration and flashover voltage was verified, and it was shown that the surface charge decay of epoxy-based model insulators is a slow process, but the decay rate increases when an outer dc electric field is applied.
Journal ArticleDOI
Charge accumulation patterns on spacer surface in HVDC gas-insulated system: Dominant uniform charging and random charge speckles
Boya Zhang,Zhe Qi,Guixin Zhang +2 more
TL;DR: In this paper, a model GIL spacer in 0.1 MPa air under DC voltage was obtained by an advanced measurement method, from which the dominant uniform charging pattern and random charge speckles were separated.
Journal ArticleDOI
Interpretation of the surface charge decay kinetics on insulators with different neutralization mechanisms
Boya Zhang,Guixin Zhang +1 more
TL;DR: In this article, the surface potential distribution was scanned in a raster mode using a Kelvin electrostatic probe, from which the relief map of charge density was obtained by an inverse calculation method.
Journal ArticleDOI
Suppression of surface charge accumulation on Al2O3-filled epoxy resin insulator under dc voltage by direct fluorination
TL;DR: In this paper, surface conductivity measurements indicated a higher surface conductivities after fluorination, which would allow the charges to transfer along the surface and thus may suppress their accumulation, and attenuated total reflection infrared analysis and surface morphology observations of the samples revealed that the introduction of fluoride groups altered the surface morphology.
Journal ArticleDOI
Fluoronitrile/CO 2 mixture as an eco-friendly alternative to SF 6 for medium voltage switchgears
Boya Zhang,Nenad Uzelac,Yang Cao +2 more
TL;DR: In this article, a comparative study of the breakdown strength and partial discharge (PD) characteristics between the fluoronitrile/CO 2 -buffer gas mixture Novec 4710 and SF 6672 was conducted under different electrode configurations, i.e., plane-plane, sphereplane, rodplane, and needleplane, at different pressures and electrode gaps.
