Fault record events

Standard events

Security Events
Standard events are further sub-categorised internally to include different pieces of information. These are:
●
Protection events (starts and trips)
●
Maintenance record events
●
Platform Events
2.2.1
OPTO-INPUT EVENTS
If one or more of the opto-inputs has changed state since the last time the protection algorithm ran (which
runs at several times per cycle), a new event is created, which logs the logic states of all opto-inputs. You
can tell which opto-input has changed state by comparing the new event with the previous one.
The description of this event type, as shown in the
Event Text
cell is always
Logic Inputs #
where # is
the batch number of the opto-inputs. This is '1', for the first batch of opto-inputs and '2' for the second batch
of opto-inputs (if applicable).
The event value shown in the
Event Value
cell for this type of event is a binary string. This shows the logical
states of the opto-inputs, where the LSB (on the right) corresponds to the first opto-input
Input L1
.
The same information is also shown in the
Opto I/P Status
cell in the
SYSTEM DATA
column. This
information is updated continuously, whereas the information in the event log is a snapshot at the time when
the event was created.
2.2.2
CONTACT EVENTS
If one or more of the output relays (also known as output contacts) has changed state since the last time the
protection algorithm ran (which runs at several times per cycle), a new event is created, which logs the logic
states of all output relays. You can tell which output relay has changed state by comparing the new event
with the previous one.
The description of this event type, as shown in the
Event Text
cell is always
Output Contacts #
where #
is the batch number of the output relay contacts. This is '1', for the first batch of output contacts and '2' for the
second batch of output contacts (if applicable).
The event value shown in the
Event Value
cell for this type of event is a binary string. This shows the logical
states of the output relays, where the LSB (on the right) corresponds to the first output contact
Output R1
.
The same information is also shown in the
Relay O/P Status
cell in the
SYSTEM DATA
column. This
information is updated continuously, whereas the information in the event log is a snapshot at the time when
the event was created.
2.2.3
ALARM EVENTS
The IED monitors itself on power up and continually thereafter. If it notices any problems, it will register an
alarm event.
The description of this event type, as shown in the
Event Text
cell is cell dependent on the type of alarm and
will be one of those shown in the following tables, followed by
OFF
or
ON
.
The event value shown in the
Event Value
cell for this type of event is a 32 bit binary string. There are one
or more banks 32 bit registers, depending on the device model. These contain all the alarm types and their
logic states (
ON
or
OFF
).
The same information is also shown in the
Alarm Status (n)
cells in the
SYSTEM DATA
column. This
information is updated continuously, whereas the information in the event log is a snapshot at the time when
the event was created.
