threshold for time longer than Mains f del.
NOTE:
The mains underfrequency protection is Mains protection type - for more
information on protection types please refer to alarm types section.
11.2.6.12 Setpoint: Mains f del
This setpoints determines the delay for mains under- (defined by Mains <f)
and overfrequency (defined by Mains >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 generator 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.
11.2.6.13 Setpoint: VectorS prot
DISABLED, PARALLEL ONLY, ENABLED [-]
This setpoint selects the function of the built-in vectorshift protection.
The vectorshift protection is disabled.
The vectorshift protection is enabled only while the
both MCB and GCB (and MGCB for applications
with MGCB) are closed.
The vectorshift protection is active always while
the MCB is closed, regardless of the GCB (and
MGCB for applications with MGCB) position.
