Water and water/ethylene glycol mixtures are being investigated for their use as high-voltage dielectrics in pulse power lines. Kerr electrooptic field mapping and voltage/current measurements have been taken with highly purified water over the temperature range 0-30 degree C using parallel plane electrodes with average field strengths up to 160 kV/cm. The Kerr constant of water B was measured to be B approximately equals 3. 4-3. 6 multiplied by 10** minus **1 **4 m/V**2 for free space light wavelength 590 nm and was found to vary only slightly with temperature over the measurement range. Photomultiplier tube measurements at 633 nm at approximately equals 10 degree C found water to have a Kerr constant B approximately equals 2. 7-2. 9 multiplied by 10** minus **1 **4 m/V**2 , while ethylene glycol had a negative Kerr constant B approximately equals -(0. 8-0. 9) multiplied by 10** minus **1 **4 m/V**2 . Water/ethylene glycol mixtures had an essentially linear variation of Kerr constant between these limits as a function of weight fractions, having a zero Kerr constant at about 79% glycol/21% water by weight. It is found that by an appropriate choice of electrode material combinations and voltage polarity, it is possible to have uncharged water, unipolar charged negative or positive water, or bipolar charged water.
