vendor.
Note: The number of digits for the power value can be reduced based on the units kW,
2
MW and kvar+. For instance, when the power is measured as "123,456kW" then it
is displayed as "123MW". If this value has to be changed then the user can key in a
new compensated value. For example, if "78MW" should be displayed on the IED
screen even though the measured value is "123,456kW" then the user should key in
the new value of "78MW". Note that the compensated value "78MW" is "78,000kW",
and it is not "78,456kW" or "123,456kW". Note that the compensated value will be
affected when there is a change in CT ratio setting. That is, when the user key in a
value of "78MW" for the CT ratio of "2000:1" and later when the CT ratio is changed
from "2000:1" to "4000:1", then the value is displayed as "156MW" on the IED screen.
Therefore when the CT ratio setting is changed, the user should key in the value of
"78MW" again to display the compensated value.
Counter sub-menu: the name and number of statistical items are shown in
two lines. When an item is revised, a [+] mark is shown at the end of the first
line.
