The default setup proposed for 3phase is the three watt meter method which requires measuring voltage between each phase and neutral.
There is an alternative method called the Two Watt Meter method. As the name suggest is uses two watt meters hence two voltage sensors and two current sensors. The voltage sensors have to be connected between two phases this time.
Library and firmware
To support TwoWattMeter the library must be RPICTlib_v1.5.2 or later.
A special firmware has been build for this purpose. You can install it with the commands below.
