Abstract:

The Franklin tester is the only standardized device that is used for the determination of the dielectric properties of electric-insulation coatings of electrical steels. It is used to measure the current value on ten electrodes with equal surface areas that contact the surface of a material; the current is then recalculated into the electric-resistance coefficient of the polarizing coating, which acts as the main characteristic of dielectric properties. It is shown that the values that are measured by a Franklin tester do not characterize the particular dielectric properties of the coating, but only indicate the presence of areas (defects) on which the coating is absent.
