“…This variation in output transmittance of light is due to the difference in refractive indices offered by nitrobenzene to the two components of electric field of light. This difference is given by [6] 2 λKE n  (1) where ∆n is the change in refractive indices offered by electro-optical birefringent material to the two perpendicular components of light, λ is wavelength of light passing …”

Abstract-High voltage pulses are much more difficult to measure precisely because of sensitivity of electrical devices to electromagnetic noise. One commonly used technique to measure high voltage pulses, is the use of Kerr cell containing any optically active material (nitrobenzene in our case). This work is based on optical technique to measure high voltage fast pulses precisely. Optical characteristics of nitrobenzene are exploited to measure the pulses. We have proposed a substitute design of Kerr cell to prevent breakdown in nitrobenzene which causes severe problems in measurement. Kerr cells of different sizes and different types are used in the experiments to measure the high voltage pulses of peak amplitude up to 100kV.Index Terms-Kerr cell, high voltage, pulse measurement, nitrobenzene, birefringence.

A comparison study between Y + 36° and 0° X-cut lithium niobate (LiNbO3) was performed to evaluate the influence of crystal cut on the acoustic propagation to realize a piezoelectric high-voltage sensor. The acoustic time-of-flight for each crystal cut was measured when applying direct current (DC), alternating current (AC), and pulsed voltages. Results show that the voltage-induced shift in the acoustic wave propagation time scaled quadratically with voltage for DC and AC voltages applied to X-cut crystals. For the Y + 36° crystal, the voltage-induced shift scales linearly with DC voltages and quadratically with AC voltages. When applying 5 μs voltage pulses to both crystals, the voltage-induced shift scaled linearly with voltage. For the Y + 36° cut, the voltage-induced shift from applying DC voltages ranged from 10 to 54 ps and 35 to 778 ps for AC voltages at 640 V over the frequency range of 100 Hz-100 kHz. Using the same conditions as the Y + 36° cut, the 0° X-cut crystal sensed a shift of 10-273 ps for DC voltages and 189-813 ps for AC voltage application. For 5 μs voltage pulses, the 0° X-cut crystal sensed a voltage induced shift of 0.250-2 ns and the Y + 36°-cut crystal sensed a time shift of 0.115-1.6 ns. This suggests a frequency sensitive response to voltage where the influence of the crystal cut was not a significant contributor under DC, AC, or pulsed voltage conditions. The measured DC data were compared to a 1-D impedance matrix model where the predicted incremental length changed as a function of voltage. When the voltage source error was eliminated through physical modeling from the uncertainty budget, the combined uncertainty of the sensor (within a 95% confidence interval) decreased to 0.0033% using a Y + 36°-cut crystal and 0.0032% using an X-cut crystal for all the voltage conditions used in this experiment.
