Event Analysis
ACSELERATOR QuickSet has integrated analysis tools that help you retrieve
information about relay operations quickly and easily. Use the event
information that the SEL-751 stores to evaluate the performance of a system
(select Tools > Events > Get Event Files). Figure 3.10 shows composite
screens for retrieving events.

Event Waveforms
QuickSet allows you to download three types of event data captures from the
relay: event reports that use 4 samples/cycle filtered data, 32 samples/cycle
unfiltered (raw) data, or high-impedance fault data. See Section 10: Analyzing
Events for information on recording events. Use the Options function in
Figure 3.10 to select the 32 samples/cycle unfiltered (raw) data event, or high-
impedance fault data (default is 4 samples/cycle filtered data).
NOTE: High-impedance fault events
are only available with the Arc Sense
technology (AST) option. The HIF
Events can take as long as an hour to
download (at 38400 baud). Increase
the baud rate before downloading.
