Applied voltage between metal electrodes, causes the ion migration, or water tree which influence on the electric resistance between electrodes. In this study, high electric voltages was applied to the Cupper electrodes, in the polymer, electric resistance was measured and electrodes was observed using stereomicroscope after testing. When high electric field (higher than 6.7MV/m) was applied between the electrodes, electric resistance suddenly fell down after some amount of time. As electric field was higher, electric resistance fell down in lower time. Stereomicroscope observation indicated that ion migration had not occurred and that it is supposed that water tree caused the drop of electric resistance of electrodes applied high electric voltage.
