Abstract:
This paper describes current and frequency range extension of AC-DC current transfer difference measurement system in CMI which is now able to measure AC-DC current differences from 1 mA up to 10 A in the frequency range 10 Hz - 100 kHz.
Since 2008 CMI has had an automated measurement set up using PMJTCs and cage shunts of own construction. This system was able to measure AC-DC current differences from 3 mA up to 10 A in the frequency range 10 Hz −10 kHz [1].
