  • Methods and apparatuses for determining the distribution of electric charge in electrical insulators produced by a sudden deformation in the insulators
    Patent number: 5247260
    Abstract: Investigation apparatus for investigating the distribution of electric charge (2) within an insulator (1) comprises: a function generator (7) suitable for generating a time-varying electrical voltage v, an amplifier (8) suitable for amplifying the voltage from the function generator, the voltage V amplified in this way being applied to the terminals of electrodes (3,4) on either side of the insulator, apparatus (9) suitable for creating sudden deformations that propagate within the insulator, a delay circuit (10) synchronized with the function generator and suitable for triggering the apparatus for creating deformations at a recurrence frequency f.sub.
