Kerr measurement approaches in propylene carbonate under DC electric field

Kerr measurement approaches in propylene carbonate under DC electric field
Kerr measurement approaches in propylene carbonate under DC electric field

An electric field between two electrodes in a dielectric liquid under high electric field stress is distorted by the presence of space charge. Besides, this phenomenon will deteriorate the performance of insulation material. In order to evaluate the distribution of the space charge, information of the distorted electric field in the insulation materials is required. This paper presents the relationship of the light intensities to the applied electric field in propylene carbonate using Kerr effect method. In the study, a pair of parallel electrodes was used as the electrodes system under DC electric field. In the preliminary experiment, the light intensity from the transmitted incident light was measured using a photodiode. Later, a high speed camera was used to capture the transmitted light intensity when an electric field was applied to the liquid. From the measurement results obtained, the light intensities were analysed and compared to the predicted light intensity ratio. Both approaches showed that the measurement results fit with the theoretical light intensity ratio curve.

Abstract

An electric field between two electrodes in a dielectric liquid under high electric field stress is distorted by the presence of space charge. Besides, this phenomenon will deteriorate the performance of insulation material. In order to evaluate the distribution of the space charge, information of the distorted electric field in the insulation materials is required. This paper presents the relationship of the light intensities to the applied electric field in propylene carbonate using Kerr effect method. In the study, a pair of parallel electrodes was used as the electrodes system under DC electric field. In the preliminary experiment, the light intensity from the transmitted incident light was measured using a photodiode. Later, a high speed camera was used to capture the transmitted light intensity when an electric field was applied to the liquid. From the measurement results obtained, the light intensities were analysed and compared to the predicted light intensity ratio. Both approaches showed that the measurement results fit with the theoretical light intensity ratio curve.
