Hi Team,
Good day.
A customer is interested to know if the MSP430F676x1A series of devices can only be used on a single 3-phase system or if it can be implemented such as to measure 3 separate single-phase systems. Do we have a document for that?
Furthermore, if the device were to measure three separate single-phase lines, can the voltage from a single of these be used to perform the power calculations on all three lines (with accepted accuracy loss)? The product he is developing is intended to be a temporary device and should be as non-invasive as possible therefore he wishes to use three current coils to measure three separate lines and tap into only one 'Live' L line for the voltages, making the assumption that the voltage seen on one of the lines will be close enough to the others.
Thank you for extending your help.
Kind regards,
Marvin
