#75962 - Rogowski Coils. |
Dear Friends,
I am stuck with current measurement using MCS-51 micro. I am planning to use rogowski coil wich will porovide me signal in proportion to rate of change of current through conductor i.e. di/dt. Now I will have to intgerate this signal in order to get a signal in proportion to i. Which then will be fed to an ADC+MCS-51 in order to get it digitized. I have worked with integrator circuit using op-Amp. Should simillar circuit be used to integrate di/dt from rogowski coils. What about the offset which will continously get integrated and will be cumullative. I will be very thankfull If you guys can please provide me some links or pointers to simillar projects or if you can provide me some hints. I know about chopper stabilised op-Amp Raghu can you please tell me what chopper stabilised Op-Amps are available easily here in India. Thank you very much. Regards, Prahlad Purohit |
