Abstract

Because of their high dielectric constant, low cost, and ease of handling and disposal, water and water/ethylene glycol mixtures are being actively investigated for use as the dielectric in pulse power capacitors, transmission lines, and switches. Ethylene glycol is used with water because it maintains high permittivity with a large resistivity and also allows low-temperature operation without freezing; thus, it can be efficiently used with long pulses and/or a high repetition rate. Recent charge injection analysis, terminal voltage-current measurements, and Kerr electrooptic field mapping measurements have shown significant space charge effects on the electric field distribution. Relevant experimental results are reported. The fundamentals of the Kerr effect are discussed, along with the magnitude and the sign of the Kerr constant.
