11.2.6.21 Setpoint: Mains I unbal
This setpoint defines the threshold for Mains current asymmetry (unbalance).
The current unbalance is calculated as a maximum difference between
phase currents. This protection is tripped with delay set by setpoint Mains
Iunb del.
11.2.6.22 Setpoint: Mains Iunb del
Delay for Mains current asymmetry (unbalance). This protection treshold is
adjusted by Mains I unbal
11.2.7 Group: Bus protect
11.2.7.1 Setpoint: Bus >V
This setpoint determines treshold for bus overvoltage protection. This
protection is evaluated with delay given by setpoint Bus V del. Protection
type is history record.
NOTE:
All three phases are checked for bus voltage detection. Maximum out of
those three is used.
For high voltage applications, the BusNomVph-ph can be used for nominal
voltage setting.
