چکیده
Abstract A used oil sample of KTPJO 10/27.5/023 power transformers which are on the railway was selected and cleaned by means electric field. This process carried out using a device assembled basis special scheme. Unrefined refined samples were tested for electrical strength, i.e. breakdown voltage, AID-70m HUAZHENG (HZJQ-X1 Transformer Oil BDV Tester) dielectric testers. The results compared analyzed regression method. It determined that operational characteristics improved.

Application of Kerr electro/optic effect to electric field measurements in transformer oils
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 re...
