Abstract :
A measuring method is presented which allows the calibration of inductive voltage dividers up to frequencies of 1 MHz. The characteristic element is an auxiliary divider with a 0.5-voltage ratio with adjustable foot and head tap voltages. Error sources due to incomplete guarding are discussed. The calibration uncertainties are ±0.3 ppm at 100 kHz and ±30 ppm at 1 MHz.
