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.
10.1.3 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
to primary peak value units when the protection relay converts the recordings to the
COMTRADE format.
COMTRADE is the general standard format used in storing disturbance
recordings.
The binary channels are sampled once per task execution of the disturbance recorder. The
task execution interval for the disturbance recorder is the same as for the protection
functions. During the COMTRADE conversion, the digital status values are repeated so
that the sampling frequencies of the analog and binary channels correspond to each other.
This is required by the COMTRADE standard.
The disturbance recorder follows the 1999 version of the COMTRADE
standard and uses the binary data file format.
