Amps Unbal Trp [%]
Threshold for generator current asymmetry (unbalance).
Step: 1% of Nominal current
Range: 1 – 200% of Nominal current
Amps Unbal Del [s]
Delay for generator current unbalance
Step: 0.1 s
Range: 0.0 – 600.0 s
Gen >V Trp [%]
Threshold for generator overvoltage. All three phases are checked. Maximum out of three is used.
Step: 1% of Nominal voltage
Range: 0(Gen <V Trp) – 200%
Gen <V Trp [%]
Threshold for generator undervoltage. All three phases are checked. Minimum out of three is used.
Step: 1% of Nominal voltage
Range: 0% – 200 (Gen >V Trp)%
