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 (PostFaultrecT and
TimeLimit).
• 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 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.
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.
