Hi guys,
I am new to this forum,so please do bear with me.
Let me convey my prob , which is on the design of an amplifier to use with a rogowski coil.I was asked to start the design and testing rogowski coil based current measurement. As a prototype , I thought of buying one rogowski coil from some coil manufacturers and design one amplifier, integrator , ADC and one cotroller circuit.For the design of an amplifeir I am really scared that what are all the expected constraints if the measurement would be in an industry where lots of inductance effect presents.Or any one of u pls suggest an amplifier circuit which I can readily use. What kind of analysis we should take care while doing an amplifier design for this particular application(with Op-amp).My aim is to measure current from 10A- 150A and frequency at 50Hz.
Please gimme a solution
Thanx in advance
Manju
