Studies For The Use Of A Dielectric Liquid As Insulator In A Wireless High Voltage Generator

We investigated the possibility to use a liquid as insulator in a High Voltage generator which is wireless powered by a laser system. The liquid must be transparent to the laser light wavelength, must not attack the control circuits, which are immersed in it, and the support materials. An adequately performing liquid was identified and we characterized the liquid performance in intense electric field, by measuring its breakdown voltage and the leakage current, and checked its optical and thermal behaviour.
