MSP430F6779: Can I measure a current without having a voltage

Ruven Dreischke

Part Number: MSP430F6779

Hello,

I am currently evaluating the MSP430F67 platform for a 3 Phase + N Rogowski current sensor application. In the Energy Measurement Design Center I can only create a phase if  there is a voltage measurement channel. I am wondering now if there is a need for that, for the measurement library to function, since I do not have a voltage to measure. Does anyone know if this the current measurement will be valid without a voltage measurement?

Thank you, kind regards,

Ruven

    Hi Ruven,

    Phase is the relationship between the voltage and current, without the voltage component you wouldn't be able to get the phase relationship. The current measurement is a reading of the voltage coming from the Rogowski coil, so the current reading itself can still be read without the voltage channel.

    Regards,
