Wayne, 1. Please note that the EVM430-F6779 does not automatically support the THD. One has to use the same EVM, but overwrite the SW with the SW available on the TIDM-THDREADING TI Design, which is on the web today. However, this TID, does not support harmonic distortion or harmonic content by the order. It calculates the total harmonic distortion versus fundamental in the measurement without breaking it down further. If one needs to get harmonic content for multiples of the fundamental, we have to do extensive processing via bandpass filtering or Frequency domain processing of the samples for voltage and current seperately. The MSP430F6779 might not have enough CPU MIPS to do harmonics for voltage and current. It maybe possible but with very limited accuracy. We have not tried it yet. 2. Currently, we do not have any 3-phase 3-wire solution on MSP today. Thanks Kripa
