Stator Current
Single- or three-phase summing-point limiter with PI control loop. Limiter has two steps…High and Low.
Setpoint Range
High, Low ................................ 100 to 300% of nominal generator output current
Definite Time Delay
High ........................................ 0 to 60 s, 1 s increments
Reactive Power
The reactive power limiter ensures that the level of var flow out of the generator does not exceed its
capability.
Setting Range (Lagging kvar)…… Determined by rated kVA specified for the controlled machine: from 0
to current value of generator rating in 1 kvar increments.
Time Delay .................................... 0 to 10 s
