The pre and post fault recording times are set by a combination of the "Duration" and
"Trigger Position" cells. "Duration" sets the overall recording time and the "Trigger Position"
sets the trigger point as a percentage of the duration. For example, the default settings
show that the overall recording time is set to 1.5s with the trigger point being at 33.3% of
this, giving 0.5s pre-fault and 1.0s post fault recording times.
If a further trigger occurs whilst a recording is taking place, the recorder will ignore the trigger
if the "Trigger Mode" has been set to "Single". However, if this has been set to "Extended",
the post trigger timer will be reset to zero, thereby extending the recording time.
As can be seen from the menu, each of the analog channels is selectable from the available
analog inputs to the relay. The digital channels may be mapped to any of the opto isolated
inputs or output contacts, in addition to a number of internal relay digital signals, such as
protection starts, LEDs etc. The complete list of these signals may be found by viewing the
available settings in the relay menu or via a setting file in MiCOM S1 V2 or MiCOM S1
Studio. Any of the digital channels may be selected to trigger the disturbance recorder on
either a low to high or a high to low transition, via the "Input Trigger" cell.
It is not possible to view the disturbance records locally via the LCD; they must be extracted
using suitable software such as MiCOM S1. This process is fully explained in the SCADA
Communications section (P746/EN SC).
