•
Should the function record faults only for the protected object or cover more?
•
How long is the longest expected fault clearing time?
•
Is it necessary to include reclosure in the recording or should a persistent fault
generate a second recording (
PostRetrig
)?
Minimize the number of recordings:
•
Binary signals: Use only relevant signals to start the recording that is,
protection trip, carrier receive and/or start signals.
•
Analog signals: The level triggering should be used with great care, since
unfortunate settings will cause enormously number of recordings. If
nevertheless analog input triggering is used, chose settings by a sufficient
margin from normal operation values. Phase voltages are not recommended for
trigging.
There is a risk of flash wear out if the disturbance report triggers
too often.
Remember that values of parameters set elsewhere are linked to the information on
a report. Such parameters are, for example, station and object identifiers, CT and
VT ratios.

The Logical signal status report (BINSTATREP) function makes it possible to poll
signals from various other function blocks.
BINSTATREP has 16 inputs and 16 outputs. The output status follows the inputs
and can be read from the local HMI or via SPA communication.
When an input is set, the respective output is set for a user defined time. If the
input signal remains set for a longer period, the output will remain set until the
input signal resets.
