NON-CONTACT METHOD OF DETERMINATION OF INDUCTIVITY OF THE SOLID AND LIQUID DIELECTRICS

FIELD: electrical measuring equipment. ^ SUBSTANCE: the invention is dealt with the field of electrical measuring equipment and may be used, for example, to check the quality of the solid and liquid insulating materials. The technical result is development of a rather simple and of high accuracy method to measure inductivity without destroying action. The method of determination of inductivity provides for action of an electromagnetic field on a specimen placed in the interelectrode space between a measuring flat electrode and a surface of a rotating metal disk, on which a polymeric film electric source of an electrical field is fixed. Then they determine the amplitude value of an inductive current of the measuring electrode in the case when the specimen is in the interelectrode space and the amplitude value of an inductive current without the dielectric placed in. The inductivity is determined by the given mathematical formula. ^ EFFECT: the invention offers a rather simple and of high accuracy method to measure inductivity without destroying action. ^ 1 dwg
