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.
3-element (Phases A, C 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.
3-element (Phases B, C 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.
2-element connection: in this
case, the neutral voltage is zero,
and the three phase-to-ground
voltage are computed based on
the two line-to-line voltages
applied to the equipment.
