Abstract :
This paper describes a method for the measurement of the level dependence in the phase angle errors of the high current shunts against a current-voltage converter with the lock-in amplifier. The measurement results of Fluke A40B and metal foil shunts developed by BEV Austria of 100 A at rated and half-rated current at 100 kHz are presented.
