Kerr effect technique is an optical measurement technique used to determine space charge distributions of a dielectric liquid under applied electric stress. In other words, such measurement can be used to study the conduction mechanisms of a dielectric liquid, such as charge injection threshold, bulk electric field stress, and aging. In this study, an instrument was set up to measure the absolute value of the electric field distributions in lead–lanthanum–zirconium–titanium (PLZT). PLZT was selected for the study of the instrumentation because the material has a high Kerr constant. In the experiment, charge injection threshold and bulk field strength of PLZT were measured under low applied voltages. © 2012 Institute of Electrical Engineers of Japan.
