Sequence of Events

A sequence of events recorder (SER) report is very useful in reconstructing the exact sequence and
timing of events during a power disturbance or even normal system operations. The SER tracks over 700
data points by monitoring the internal and external status of the BE1-11g. Data points are scanned every
quarter-cycle. All changes of state that occur during each scan are time tagged to 1 millisecond
resolution. Over 1,000 records are stored in nonvolatile memory; when the SER memory becomes full,
the oldest record is replaced by the latest one acquired.
The SER monitors the following points and conditions:
•
Single-state events such as resetting demands or targets, changing settings, etc.
•
Programmable logic variables
•
Targets
•
Relay trouble alarm variables
•
Programmable alarm variables
•
Output contact status
•
Fault reporting trigger expressions
BE1-11g protection systems have three identification fields: Device ID, Station ID, and User ID. These
fields are used in the header information lines of the sequence of events records. Refer to the
BESTCOMSPlus® Software chapter for information on BE1-11g identification settings.
For user-programmable logic variables (contact sensing inputs, contact outputs, and virtual control
switches), the user-programmed variable name, and state names are logged in the SER report instead of
the generic variable name and state names.
When a monitored event occurs or a monitored variable changes state, the SER logs all event data listed
in Table 78.
