17.6.3.5 Consideration
The density of recording equipment in power systems is increasing, since the number of modern
IEDs, where recorders are included, is increasing. This leads to a vast number of recordings at
every single disturbance and a lot of information has to be handled if the recording functions do
not have proper settings. The goal is to optimize the settings in each IED to be able to capture just
valuable disturbances and to maximize the number that is possible to save in the IED.
The recording time should not be longer than necessary (
• 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 (
Minimize the number of recordings:
• Binary signals: Use only relevant signals to start the recording that is, protection trip, carrier
receive and/or pickup 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.
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.
17.7 Logical signal status report BINSTATREP
17.7.1 Identification
Function description
Logical signal status report
17.7.2 Application
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.

There is a risk of flash wear out if the disturbance report triggers too often.
