Electric field distribution in fluid dielectric using optical method
Electric field distribution in fluid dielectric using optical method
The electrical performance of the high voltage insulation materials can be affected by the presence of space charge. In order to evaluate the space charge distribution, prior information of the electric field distribution in the insulation materials is needed. Mainly, the study aims to investigate methods for quantifying space charge in dielectric liquids under uniform and non-uniform fields. In liquid dielectrics, an optical method known as Kerr Electro-optic effect has been developed for measuring the electric field distributions under high voltage stress .Generally, this method requires a constant electric field magnitude and direction along the optical light path in quantifying the electric field distribution relatively to the measured light intensity. However, the method can be extended with approximated assumptions for determining the varying electric field within non-uniform electric field distributions in the liquid dielectrics.

Abstract
The electrical performance of the high voltage insulation materials can be affected by the presence of space charge. In order to evaluate the space charge distribution, prior information of the electric field distribution in the insulation materials is needed. Mainly, the study aims to investigate methods for quantifying space charge in dielectric liquids under uniform and non-uniform fields. In liquid dielectrics, an optical method known as Kerr Electro-optic effect has been developed for measuring the electric field distributions under high voltage stress .Generally, this method requires a constant electric field magnitude and direction along the optical light path in quantifying the electric field distribution relatively to the measured light intensity. However, the method can be extended with approximated assumptions for determining the varying electric field within non-uniform electric field distributions in the liquid dielectrics.
