Abstract An instrument which measures current from D.C. to 50 megahertz
by clipping a transformer core around a current carrying conductor
is discussed. A Hall device, which is installed in the core cross-section, detects the flux in the core. This Hall device in conjunction
with an amplifier is used to null the low frequency components
of flux generated in the core by the current in the conductor. A
multi-turn secondary winding performs the same type of operation at
high frequencies. The current generated by these two methods, which
is proportional to the input current, is amplified and measured with
an oscilloscope or other suitable instrument. The mode of operation
and the characteristics of the system are analyzed, with emphasis
upon the midfrequency range. Results of measurements from an operating
system are given and correlation to the model is shown.
