C2000WARE-DIGITALPOWER-SDK: Is the input voltage in Sine Analyzer with Power Measurement Module..L-L? L-N?

Part Number: C2000WARE-DIGITALPOWER-SDK

Hi.

typedef volatile struct {
    float32_t v;           //!< Input: Voltage Sine Signal
    float32_t i;           //!< Input Current Signal
    float32_t sampleFreq;  //!< Input: Signal Sampling Freq
    float32_t threshold;   //!< Input: Voltage level corresponding to zero i/p
    ...
}

Is the Voltage Sine Signal L-L? L-N?

My system is below...

Only R-S line voltage and S-T line voltage are sensed.

The T-R line voltage and each phase voltage are calculated.

sense_grid_ab_v = R-S ADC Value

sense_grid_bc_v = S-T ADC Value

sense_grid_ca_v = (-1.0) * (sense_grid_ab_v + sense_grid_bc_v); // calculation value

//calculate L-L to L-N
calc_grid_a_v = (sense_grid_ab_v - sense_grid_ca_v) * (float) 0.333333333;
calc_grid_b_v = (sense_grid_bc_v - sense_grid_ab_v) * (float) 0.333333333;
calc_grid_c_v = (sense_grid_ca_v - sense_grid_bc_v) * (float) 0.333333333;

Which of the above voltage values is float32_t v; //!< Input: Do I need to connect to Voltage Sine Signal?

Thanks.
