“…1,2 Voltage sensors based on electro-optical crystals such as Bi 4 Ge 3 O 12 , bismuth silicate and LiNbO 3 have been applied in high voltage systems [3][4][5][6][7][8] because of their wide operating bands, rapid response characteristics, low electromagnetic interference characteristics, and low optical transmission loss. However, some of these sensors have high half-wave voltages and low electro-optic coefficients, and are less sensitive to low voltage signals.…”

Voltage sensors based on the Pockels electro-optic effect in LiNbO 3 crystals have been applied to practical engineering measurements because of their passive nature, wide operating bands, and low transmission loss. However, the temperature of the measurement environment can greatly affect the dynamic responses of these sensors because the natural birefringence of a single LiNbO 3 crystal voltage sensor (SVS) is related to its temperature. To improve the stability of this sensor over a wide temperature range, a double crystal compensation method is introduced in this paper to compensate for the natural birefringence of the SVS. A double LiNbO 3 crystal voltage sensor (DVS) was fabricated, and its working point drift characteristics and amplitude-frequency response were investigated over the temperature range from 0 • C to 50• C. The effects of two intrinsic parameters of the LiNbO 3 crystal were also investigated. Comparison between an existing SVS and the proposed DVS showed that the DVS resisted environmental temperature fluctuations more strongly. C 2016 Author(s).

“…Capacitance or resistance connect hollow coil or small current transformer has no active power consumption, but it can be influenced for the precision in a certain extent by environmental factors such as temperature, magnetic field etc. Optical voltage sensing technology mainly uses the physical characteristics of optical materials mainly includes electronic voltage transformer technology based on Pockels effect and inverse voltage effect, however, due to the high demand for materials and equipment, the crystal is easy to be affected by vibration, environmental temperature and other factors, the stability and reliability need to be further strengthened [3,4]. This paper proposes an AC high-voltage measuring system based on high voltage standard capacitor.…”

Intense transient electric field measurements are widely applied in various research areas. An optical intense E-field sensor for time-domain measurements, based on the electro-optic effect of lithium niobate, has been studied in detail. Principles and key issues in the design of the sensor are presented. The sensor is insulated, small in size (65 mm × 15 mm × 15 mm), and suitable for high-intensity (<801 kV/m) electric field measurements over a wide frequency band (10 Hz–10 MHz). The input/output characteristics of the sensor were obtained and the sensor calibrated. Finally, an application using this sensor in testing laboratory lightning impulses and in measuring transient electric fields during switch-on of a disconnector confirmed that the sensor is expected to find widespread use in transient intense electric field measurement applications.
