The Measurement of DC Electric Field for Transformer Oil System Based on the Kerr Electro-Optic Effect

Abstract:

This study presents a effective approach for the measurement of electric field in liquid dielectric with small Kerr constant based on the principle of Kerr electro-optic effect. In the paper, the distribution of electric field in transformer oil is measured of different electrode materials below 30KV. According to experiments it can be concluded that the intensity of light corresponds with the electric field between the two parallel-plane electrodes in test cell in a certain range of the voltage applied. The conclusion reveals that the distribution and variation tendency of the electric field between the two electrodes can be drawn by the analysis of the light intensity.
