Overview of Functions

The Fast-scan recorder records individual current and voltage sampled values at a sampling rate that is high
enough for the display of network events and transients.
The fast-scan recorder records at least 1 s up to a maximum of 90 seconds. The sampled values (SAV) are
always routed automatically to the Fast-scan recorder.
The fault record generated contains the following information:
•
Pre-trigger time
•
Trigger point
•
Fault Recording
•
Trigger end mark (if a falling trigger is detected)
•
Post-trigger time (if a falling trigger is detected)
In addition, the cause that trips the trigger is saved.
