Tentative type test of a non-invasive high-voltage meter with respect to the quantity of practical peak voltage

Beschreibung

In Working Group 3 of Sub-committee 62C of the International Electrotechnical Commission (IEC) a new project is underway with the objective of specifying requirements for the performance characteristics of instruments for the non-invasive measurement of the X-ray tube voltage in diagnostic radiology. In this draft the X-ray tube voltage is specified in terms of the practical peak voltage. The objective of the present work is to perform a tentative type test, based on the "Requirements for Instruments for Non-invasive Measurements of the X-ray Tube Voltage" defined in the IEC draft, with a commercially available non-invasive high-voltage meter. The instrument was modified so that the practical peak voltage can be measured. It is shown that the instrument, with the modifications made, is suitable for the non-invasive measurement of the practical peak voltage between 50 kV and 150 kV within the required limits of variation of the response.
