Condenser shunt for measurement of high-frequency currents of large magnitude

B. E. Lenehan: It is not apparent why the capacity of a condenser can be assumed to be constant up to frequencies as high as 6000 kilocycles. Two conductors spaced approximately 10 times their diameter will have an inductive drop at 50 amperes 6000 kc. of about 345 volts per ft. The mutual inductance between the meter and shunt circuit can hardly be disregarded as only 1 per cent coupling would introduce errors of around 50 per cent.
