Measurement of the equivalent inductance of the high current shunts

We describe a method for the measurement of the equivalent inductance of the high current shunts against a four-terminal mutual inductance with the lock-in amplifier by means of the substitution method. The measurement results of Fluke A40B and metal foil shunts developed by BEV Austria at 50 A and 100 A at frequency up to 200 kHz are presented.
