2 EVENT RECORDS
General Electric devices record events in an event log. This allows you to establish the sequence of events that led
up to a par
ticular situation. For example, a change in a digital input signal or protection element output signal
would cause an event record to be created and stored in the event log. This could be used to analyse how a
particular power system condition was caused. These events are stored in the IED's non-volatile memory. Each
event is time tagged.
The event records can be displayed on an IED's front panel but it is easier to view them through the settings
application software. This can extract the events log from the device and store it as a single .evt file for analysis on
a PC.
The event records are detailed in the VIEW RECORDS column. The first event (0) is always the latest event. After
selecting the required event, you can scroll through the menus to obtain further details.
If viewing the event with the settings application software, simply open the extracted event file. All the events are
displayed chronologically. Each event is summarised with a time stamp (obtained from the Time & Date cell) and a
short description relating to the event (obtained from the Event Text cell. You can expand the details of the event
by clicking on the + icon to the left of the time stamp.
The following table shows the correlation between the fields in the setting application software's event viewer and
the cells in the menu database.

The device is capable of storing up to 1024 event records.
In addition to the event log, there are two logs which contain duplicates of the last 5 maintenance records and the
last 5 fault records. The purpose of this is to provide convenient access to the most recent fault and maintenance
events.
