Figure 300: The recording times definition
PreFaultRecT, 1 Pre-fault or pre-trigger recording time. The time before the fault including the operate time
of the trigger. Use the setting
PreFaultRecT to set this time.
tFault, 2 Fault time of the recording. The fault time cannot be set. It continues as long as any valid
trigger condition, binary or analog, persists (unless limited by TimeLimit the limit time).
PostFaultRecT, 3 Post fault recording time. The time the disturbance recording continues after all activated
triggers are reset. Use the setting
PostFaultRecT to set this time.
TimeLimit Limit time. The maximum allowed recording time after the disturbance recording was
triggered. The limit time is used to eliminate the consequences of a trigger that does not
reset within a reasonable time interval. It limits the maximum recording time of a recording
and prevents subsequent overwriting of already stored disturbances. Use the setting
TimeLimit to set this time.
14.4.6.10 Analog signals
Up to 40 analog signals can be selected for recording by the Disturbance recorder and
triggering of the Disturbance report function. Out of these 40, 30 are reserved for external
analog signals from analog input modules via preprocessing function blocks (SMAI) and
summation block (3PHSUM). The last 10 channels may be connected to internally
calculated analog signals available as function block output signals (phase differential
currents, bias currents and so on).
