Application of Kerr electro/optic effect to electric field measurements in transformer oils
نویسندگان
چکیده
Paper presents an original method suitable for measurement of electric field distribution in liquid dielectrics (nanosecond time domain). Electric field is reconstructed in two steps: 1) multiangular laser scanning of the space between electrodes provides projection for each laser beam, 2) using a numerical algorithm called Modified Aritmetic Reconstruction Technique (MART) electric field is reconstructed in the plane of laser scanning. Finite Difference Method (FDM) is used to compare and verify experimental results for a symmetrical and asymmetrical electrode configurations. Comparison of experimental (Computerized Laser Tomography) and numerical approach (FDM), confirmed that experimental approach is accurate enough to be used in initial design of many oilimmersed dielectric system.

Keer electro-optic measurements in liquid dielectrics
Kerr electro-optic technique has been used to measure the electric field distribution in high voltage stressed dielectric liquids, where the difference between refractive indices for light polarized parallel and perpendicular to the local electric field is a function of the electric field intensity. For transformer oil, the most widely-used insulating liquids in power apparatus and high voltage...
متن کاملFinite Element Based Kerr Electro-optic Reconstruction of Space Charge
Recently we used the onion peeling method to reconstruct the axisymmetric electric field distribution of point/plane electrodes from Kerr electro-optic measurements. The method accurately reconstructed the electric field from numerically generated data. However in the presence of experimental noise the performance was less satisfactory. The measurements were especially noisy and unstable near t...
متن کاملComparative Study of Theoretical Kerr Electro-optic Fringe Patterns in 2-D and Axisymmetric Electrode Geometries
Kerr electro-optic fringe patterns have long been used to study space charge injection and transport phenomena in highly birefringent materials such as nitrobenzene. Most past experimental work has been limited to 1 or 2-dimensional geometries where the electric field magnitude and direction have been constant along the light path such as two concentric or parallel cylinders or parallel plate e...
متن کاملHigh accuracy Kerr effect measurement technique
Apparatus and techniques are demonstrated which allow gas phase dc electro-optic Kerr effect measurements to be made with 0.1% absolute accuracy and nanoradian sensitivity. Measurements of the electric-field-induced birefringence of a gas are calibrated against a liquid Kerr cell, which is in turn calibrated absolutely in situ. Some of the problems addressed in this work are control of stray bi...
