Underexcitation
User-selectable, summing-point type or takeover limiter. UEL curve is selected by specifying the
acceptable reactive power level at zero active power output or by entering a five-point UEL characteristic.
UEL adjusts characteristic according to changes in generator terminal voltage.
Reactive Power
Setting Range ......................... 0 to 41 kvar (leading)
Setting Increment.................... 1 kvar
Real Power
Setting Range ......................... 0 to 41 kW
Setting Increment.................... 1 kW
