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.
