Abstract:
This thesis is an investigation of surface charge accumulation and the
role it plays in
surface flashover. Most predominantly this thesis has investigated
the role surface charge
accumulation has on surface flashover of an XLPE insulated conductor.
In brief it was found that
- Surface charge does occur on XLPE insulation.
- Surface charge accumulation is greatest when a withstand voltage
is applied.
- There is very little surface charge accumulation when a flashover
occurs, this
indicates that a flashover neutralises most of the accumulated charge.
- Surface charge accumulation served to increase the flashover voltage.
- The breakdown voltages were much greater for an air gap set-up than
the flashover
voltages for the insulated conductor set-up.
