The number of restrikes can be decreased significantly by using a bipolar load current arc conditioning.

So far, it is not very clear why the delayed postarc restrikes occur. In this thesis, two kinds of restrikes have been discovered through prebreakdown current measurment and analyses,(1) the abrupt breakdown, it is characterized by a suddenly appeared, with a period of a few microsecond prebreakdown current, it is initiated by particle. This kind of restrikes can be reduced by decreasing loosly adhesive clumps which drop into the gap after arc extinction.

In this thesis, the load current arc conditioning effect on the postarc restrikes has been investigated by using a synthetic circuit, experiments show that the restrikes can be decreased by using arc conditioning process with polarity effect.
