Abstract
The influence of conducting particles on the corona onset voltage and the breakdown voltage in a uniform field gap under AC voltage superimposed with negative DC biasing voltage is investigated. The effect of particle length, gap spacing and the DC biasing voltage on the corona onset and the breakdown voltages is also presented and discussed. The breakdown voltage of different gap spacing and DC biasing voltage is compared with calculated values. The comparison shows good agreement between experimental and calculated values
