configurable. It can be modified by writing the new name to the Channel id text parameter
of the corresponding analog channel.
Any external or internal digital signal of the protection relay which can be dynamically
mapped can be connected to the binary channels of the disturbance recorder. These signals
can be, for example, the pickup and trip signals from protection function blocks or the
external binary inputs of the protection relay. The connection is made with dynamic
mapping to the binary channel of the disturbance recorder using, for example, SMT of
PCM600. It is also possible to connect several digital signals to one binary channel of the
disturbance recorder. In that case, the signals can be combined with logical functions, for
example AND and OR. The name of the binary channel can be configured and modified
by writing the new name to the Channel id text parameter of the corresponding binary
channel.
Note that the Channel id text parameter is used in COMTRADE configuration files as a
channel identifier.
The recording always contains all binary channels of the disturbance recorder. If one of
the binary channels is disabled, the recorded state of the channel is continuously FALSE
and the state changes of the corresponding channel are not recorded. The corresponding
channel name for disabled binary channels in the COMTRADE configuration file is
Unused BI.
To enable or disable an analog or a binary channel of the disturbance recorder, the
Operation parameter of the corresponding analog or binary channel is set to "Enable" or
"Disable".
The states of manual triggering and periodic triggering are not included in the recording,
but they create a state change to the Periodic triggering and Manual triggering status
parameters, which in turn create events.
The TRIGGERED output can be used to control the indication LEDs of the protection
relay. The TRIGGERED output is TRUE due to the triggering of the disturbance recorder,
until all the data for the corresponding recording has been recorded.
The IP number of the protection relay and the content of the Bay name
parameter are both included in the COMTRADE configuration file for
identification purposes.

Application

The disturbance recorder is used for post-fault analysis and for verifying the correct
operation of protection relays and circuit breakers. It can record both analog and binary
signal information. The analog inputs are recorded as instantaneous values and converted
