Technical Manual
The
Recording started
parameter can be used to control the indication LEDs of the IED.
The output of the
Recording started
parameter is TRUE due to the triggering of the digital
fault recorder, until all the data for the corresponding recording is recorded.
9.1.3
Application
The digital fault recorder is used for post-fault analysis and for verifying the correct
operation of protection IEDs 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 IED converts the recordings to the COMTRADE
format.
The binary channels are sampled once per task execution of the digital fault recorder. The
task execution interval for the digital fault 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 IP number of the IED and the content of the
Bay name
parameter are
both included in the COMTRADE configuration file for identification
purposes.
COMTRADE is the general standard format used in storing disturbance
recordings.
The digital fault recorder follows the 1999 version of the COMTRADE
standard and uses the binary data file format.
