0.1 s
The Maximum Record time configures the maximum duration that the register can reach. If consecutive
retriggers or a sustained fault happens, the Maximum Record time establishes the limit of time that the
COMTRADE file will register.
The maximum duration of the disturbance record is 20 minutes.
3.3 SAMPLING RATE
The trigger and continuous recorder sampling rate is one-per-cycle.
3.4 RE-TRIGGER AND RECORD CONCATENATION
Two records will be concatenated if the disturbance recorder is re-triggered and there is an overlap between
the post-fault time of the first record and the pre-fault time of the second record.
3.5 TRIGGER BURST LIMITER
There is an user-configurable trigger burst limiter for the disturbance recorder which is identical to the fault
recorder limiter.
