MainsPro Reference Guide
V> 460 V
V>> 0 (OFF)
V< 340 V
V<< 160
NOTE:
Please note, that the indicated setting is adjusted for "Star" connection of the measured voltage, i.e.
ph-to-N voltage measurement. In case of using "Delta" connection, the appropriate change of the
setpoints to ph-ph voltage is necessary.
V> del, V>> del, V< del, V<< del [s]
Delay of the appropriate stage of the voltage protection.
Range: 0,00..600,00 s
Default setting:
V> Del 0,20s
V>> Del 2,50s
V< Del 0,40 s
V<< Del 0,20 s
Avg V> [V]
Limit for floating 10 minutes average overvoltage protection.
Range: 0..34000 V
0 = OFF, the 10 minutes average overvoltage protection is not enabled
Default setting: 440
RstV>,V>> [%V>]
Voltage level at which the protection activates again after a trip caused by overvoltage. The TRIP
status will be terminated.
Range: 90 - 100 %V>
0 = OFF, the reset threshold is not activated
Default setting: 100 %V>
RstV<,V<< [%V<]
Voltage level at which the protection activates again after a trip caused by undervoltage. The TRIP
status will be terminated.
Range: 100 - 110 %V<
0 = OFF, the reset threshold is not activated
Default setting: 100 %V<
dU, A.dU
V unb, A.V unb [V]
Threshold of the voltage unbalance (amplitude asymmetry). The value corresponds to the maximum
difference between highest and lowest RMS phase voltage of the 3-phase system.
Range: 0..999 V
0 = OFF, the amplitude asymmetry is disabled
Default setting: 0 = OFF
V< pos, A.V< pos [V]
Threshold of the positive sequence undervoltage (angle asymmetry method).
