High Frequency Current Measurement

I have an application where i need to measure current signals with frequency 2 mhz to 5 mhz.

High frequency current measurement.

Since this type of ac dc zero flux current sensing functions as a ct in the high frequency region it can deliver a broad frequency band. Design philosophy and important characteristics of sensors for measure of voltage up to 10 kv and current up to 400 a at frequency 1 7 1 9 mhz are describes in the paper. Pem produce ac current probes with a very wide bandwidth capable of measuring from sub 1hz into the mhz range. It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters ten to one hundred meters.

At hyteps we have noticed an increasing number of complaints from the industry regarding high frequency currents and voltages. Frequencies immediately below hf are denoted medium frequency mf while the next band of higher frequencies is. We cannot restrict ourselves to measuring only the regular harmonic voltages and currents which are defined up to a frequency of 2 5khz the 50 th harmonic. Measuring and analysing high frequency currents and voltages.

Measuring high frequency large magnitude sinusoidal currents. The current signal variation will be in the order of few micro amperes. Since detection is performed by a hall element this type of ac dc zero flux current sensor can detect magnetism produced by dc current and it can measure dc current.
