Abstract
A method and device applicable to HV generators and X-ray tubes, and a computer program and support for the program. In the method a determination is made of a scale of values representing the energy of the radio-frequency spectrum transmitted by radio wave over a given period in the electric discharges appearing in the system for a given test voltage, by artificially varying in the system the level of pollution of the system until dielectric failure of the system. A limiting value is chosen embracing the admissible pollution tolerances on manufacture. A measurement is made for each system of the same product type of the quantity of energy of the radio-frequency spectrum transmitted by radio wave by each of the systems under the same conditions. A comparison is made of the quantities measured with the limiting value chosen to determine a possible fluctuation of quality of the systems produced.
