6.2.7.1
Voltage and current multipliers
The voltage and current multipliers do not affect the regulation of the
control. They are only used in the calculation of primary values.
The use of a voltage correction factor is incorporated in the calculation of
primary quantities in the control. Although the control operation is not
affected, erroneous values will be displayed and recorded if the VT
correction factor is not included in the PT multiplier.
Primary quantities are displayed when voltage and current multipliers are set in the
control. The voltage multiplier is:
V
mult
= V
pri
/(V

+ V

)
For a VT ratio of 7620/117 V and a voltage correction of 3 V, the multiplier is:
