Working groups are presently engaged in preparing a standard on digital recorders for measurement in HV impulse tests. This paper shows how the main tests described in the proposed standard can be applied towards qualifying an impulse digitizer for HV Impulse measurements. Experimental results from the application of these techniques to different digitizers are presented. A major problem in using digital recorders in HV laboratories is electromagnetic interference. Previous low frequency measurements have indicated that high frequencies can be a problem and this paper reports some measurements at high frequencies. The consequences of these measurements for electromagnetic compatibility are discussed.
