Monitoring
This method of checking the analog trigger conditions gives a function which is insensitive to DC
offset in the signal. The trip time for this initiation is typically in the range of one cycle, 16 2/3 ms
for a 60 Hz network.
All under/over trig signal information is available on the local HMI and PCM600.
Post Retrigger
Disturbance report function does not automatically respond to any new trig condition during a
recording, after all signals set as trigger signals have been reset. However, under certain
circumstances the fault condition may reoccur during the post-fault recording, for instance by
automatic reclosing to a still faulty power line.
In order to capture the new disturbance it is possible to allow retriggering (
during the post-fault time. In this case a new, complete recording will pickup and, during a period,
run in parallel with the initial recording.
When the retrig parameter is disabled (
until the post-fault (
the post-fault period and lasts longer than the proceeding recording a new complete recording
will be started.
Disturbance report function can handle maximum 3 simultaneous disturbance recordings.
