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

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.
In circuits of one element, the measurements can be in two different ways:
An isolated phase or neutral measurement: If the element is a phase, only the voltage
related to this channel is measured considering the off-set compensation. If the
element is a neutral, the voltage related to this channel is measured without the off-
set compensation.
A 3-Phase synthesis: The magnitude for the 3-phases is considered with the same
value as that of the channel measured and balanced (i.e., angles with 120º between
each other).
