High Current Measurement

[Mohsen]

Hi

Is it possible to measure high current(say 20kA)to use in a feedback
loop?


Thanks.

Sure. For something slow like a plating process it's not difficult.

Sure. What accuracy and bandwidth did you have in mind ?

Hall effect sensors are available that should do the job. They have
high bandwidth. See, for example:

Hi

I want to measure a sinusoidal 50 Hz current. I want to use hysteresis
current control; therefore the output current has harmonics at
switching frequency (e.g 10 KHz). I have not any accuracy in my mind.


Thanks.
