The performance of a high-voltage pulse measuring system based on the Kerr effect is investigated with benzoyl chloride, o-nitrotoluene, acetophenone, acetonitrile, benzaldehyde and ethyl methyl ketone for the first time along with nitrobenzene and acetone that are well known. These investigations have been carried out using high-voltage pulse fields ranging from 4*105 V m-1 to 107 V m-1. The experimentally determined electric field from the Kerr signal and the applied field show good agreement.read more

High Voltage Pulse Measuring System Based on Kerr Effect
S. Y. Ettinger,A. C. Venezia +1 more
TL;DR: The voltage measuring system described in this paper is based on the electro-optical Kerr effect, where variations in the voltage magnitude will result in respective changes in the intensity of a light beam passing through the Kerr cell perpendicularly to the applied field.
