For different surface roughness of electrodes and glycol concentration of glycol/water mixture, pressurized water breakdown experiments are carried out. Experimental results suggest that Mirza's formula is valid and independent of surface roughness and glycol concentration, and it is accumulative for surface polish, glycol additive, and pressurization for the capability to improve electrical breakdown strength. Moreover, the increase of electrical breakdown strength of water dielectric for surface polish is explained with bubble breakdown. Especially, highest stress of 235.5kV/cm observed in glycol/water mixture with a glycol concentration of 80% at a hydrostatic pressure of 12atm is about one time greater than that in pure water at constant pressure.

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.
