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.
