2 CONNECTION DIAGRAMS OF THE VOLTAGE INPUTS
The RPV311 provides the capability for making some different voltage signal connections for a 3-phase
circuit:
Connection diagram of the voltage inputs
4-element connection: in this case, the values
shown are equivalent to the voltages of phases A,
B and C, and to the neutral voltage applied to the
equipment.
3-element (Phases A, B and C) connection: in
this case, the fourth element is derived of the
values measured by the other elements. The three
elements are equivalent to the values applied to
the equipment
3-element (Phases A, B and neutral)
connection: in this case, the fourth element is
synthesized of the values measured by the other
elements. The three elements are equivalent to the
values applied to the equipment.
