11.2.7.2 Setpoint: Bus <V
This setpoint determines treshold for bus undervoltage 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. Minimum out of those
three is used.
For high voltage applications, the BusNomVph-ph can be used for nominal
voltage setting.
11.2.7.3 Setpoint: Bus V del
This setpoint adjusts delay for under- (Bus <V) and overvoltage (Bus >V)
protections.
NOTE:
Although the resolution of this setpoint is 0.01s, in fact the adjusted delay is
rounded to the next higher multiple of the period of the bus voltage. The
period is either 0.02s for 50Hz systems or 0.0166s for 60Hz systems. E.g. if
the delay is set to 0.03s at 50Hz system the real delay will be 0.04s.
