•This is the highest value of the calculated secondary voltage at the center of regulation
during reverse power flow since last reset, as a demand value, according to the demand
time interval at FC 46.
•The reverse line-drop compensation settings for resistance and reactance (FC 54 and FC 55)
are used in calculating this value.
•Date and time of the occurrence of the highest compensated voltage is displayed.
•The control requires source voltage from a differential or source potential transformer or
from the source voltage calculation (see FC 39) to obtain this parameter. Lack of this
voltage will result in the parameter displaying dashes.
