This paper describes a system set up to provide calibrations of the digital recorders used in high voltage measurements. A high voltage impulse can be up to several megavolts peak and a few microseconds long. A high voltage divider is used to reduce the voltage to a measurable level. The output of the divider is read by a digital recorder. The calibrations are in accordance with the requirements of EN 601083-1 and cover (1) Timebase (2) Risetime (3) Impulse scale factor (4) Static and dynamic non-linearity (5) Internal noise level (6) Ripple tests (7) Static scale factor The measurements described were made on a Nicolet Power Pro 610 instrument but the principles are applicable to any instrument.
