Figure 33 Plots Screen
The bottom panel displays a list of events with the date-time stamp of the event. The STS records
waveforms for up to 25 events.
These events generate waveform plots:
•
Outages (automatic transfers due to a source going out of specification)
•
Dual outages, where both sources fail
•
Manual transfers
•
Immediate user-requested plot (

.
The scroll bar on the right of the event list panel allows the user to scroll through the event list to display
the waveform captures for a specific event.
The top four panels are the plots associated with the currently highlighted event. These four panels
display the three phases of each source and output as waveforms captures. The waveforms are color-
coded for each phase: Phase A is blue, Phase B is red, and Phase C is black. These displays show
breaks in the waves if there has been an outage or a transfer.
