)
If the conditions defined by the user - using the graphic equation editor – are satisfied, then
the disturbance recorder starts recording the sampled values of configured analog signals
and binary signals. The analog signals can be sampled values (voltages and currents)
received via input modules or they can be calculated analog values (such as negative
sequence components, etc.) The number of the configured binary signals for recording is
limited to 64. During the operation of the function, the pre-fault signals are preserved for the
time duration as defined by the parameter
“ PreFault ” . The fault duration is limited by the
parameter “ MaxFault ” but if the triggering signal resets earlier, this section is shorter. The
post-fault signals are preserved for the time duration as defined by the parameter “ PostFault
” . During or after the running of the recording, the triggering condition must be reset for a
new recording procedure to start.
The records are stored in standard COMTRADE format.
•
The configuration is defined by the file .cfg,
•
The data are stored in the file .dat,
•
Plain text comments can be written in the file .inf.
The procedure for downloading the records includes a downloading of a single compressed
.zip-file. Downloading can be initiated from a web browser tool or from the software tools.
This procedure assures that the three component files (.cfg, .dat and .inf) are stored in the
same location. The evaluation can be performed using any COMTRADE evaluator software,
e.g. Arcteq’s AQview software. Consult your nearest Arcteq representative for availability.
