Help me make a current pulse on loop detector

current pulse detector

I need make circuit for detect current pulses on loop. Loop has voltage source and loop current can be variable (0-1A). Current pulses are superimposed with aproximated value 15mA.

Any idea or inspiration?

Thanks!

Re: current pulse detector

In general you will have to use a high pass filter to separate the pulse from the background.

Try use a current transformer.

Hi.

When I need to measure a current in a circuit, I insert a resistor of small value in the circuit and read the voltage drop between the inserted resistor
by using the Op Amp. When the voltage at the driving port is important,
I used to use two lines; one is the voltage forcing line and the other is voltage sensing line. This method is widely used in the measurement equipments.

I wish this reply to be some idea to solve your problem.
Bye~~~

Use a rogowski coil.
