3-Ф Wye IT
The logger has a galvanic isolation between the voltage inputs and
ground based signals like USB and mains input.
Example: Industrial power in countries that use the IT (Isolated Terra)
system, such as Norway.
Energy Study
Load Study (no voltage measurement)
3-Ф Wye Balanced
Example: For symmetrical loads like motors the connection can be
simplified by measuring only one phase and assuming the same
voltages/currents on the other phases.
