CONNECTION DIAGRAM OF THE CURRENT INPUTS
The RPV311 provides the capability for connecting some different current signal connections for a 3-phase
circuit:
Connection diagram of the current 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
derived of the values measured by the other
elements. The three elements are equivalent to
the values applied to the equipment.
