This setpoint determines the treshold for bus overfrequency protection. This
protection is evaluated with delay given by setpoint Bus f del and it is history
record type.
11.2.7.5 Setpoint: Bus <f
This setpoint determines the treshold for bus underfrequency protection. This
protection is evaluated with delay given by setpoint Bus f del and it is history
record type.
11.2.7.6 Setpoint: Bus f del
This setpoint adjusts delay for under- (Bus <f) and overfrequency (Bus >f)
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.
