4.4.2 EVENT RECORDER
Actual – Event Recorder
option makes the last 24 relay events to be retrieved (up to 32) and displayed in the window
appearing in Figure 4–16:. Each event record is labeled with date, time (with 1msec. resolution), the cause of the event
(pickup, trip of a certain function, etc.), and a list of the status of all inputs, outputs and functions during the event.
Additionally, the program also shows current and voltage values for all phases and ground, frequency and single line
sequence voltage during the event.
Figure 4–16: EVENTS WINDOW
The retrieved events can be reviewed in this window or also saved to disk (to be opened with ENERVISTA MII SETUP
program) or exported to CSV (Comma Separated Values) format. This is a standard text table format that can be opened
with most commercially available database or spreadsheet programs such as MS Access or Excel.
