Abstract :
The established ac-dc current transfer standards and measurement set-ups of EC, IEN, LCIE, PTB, SP and VSL were intercompared in the current range from 10 mA to 20 A and in the frequency range from 10 Hz to 100 kHz. An agreement within 10 ppm to 30 ppm was obtained up to 100 mA, degrading to 100 ppm at 1 A (100 kHz) and 70 ppm at 10 A (20 kHz) and 20 A (5 kHz).<>
