MEASUREMENTS, LOGICAL STATES AND COUNTERS
• Set the pre-trigger and post-trigger intervals
• Select the sampled measurements to be logged.
• Assign the analogue measurement channels (1...12) to the measurements to be logged.
• Assign the digital measurement channels (1...12) to the measurements to be logged (status of
output relays / logical inputs).
• Select the signals which trigger logging; the measurements are saved automatically when the user
selected signal changes state (start / trip of a protection function, change of state of output relays/
logical inputs).
COMTRADE
The logs are saved in the COMTRADE (Common Format for Transient Data) format; this is an IEEE
standard (C37.111) which denes the format for the les and the logging criteria for transient fault
data in electrical power systems.
The standard also denes the structure of the header le (.HDR), conguration le (.CFG) and data
le (.DAT) use to exchange data.
The standard is included as IEC 60255-24 in the collection of standards governing protection relays;
for a complete treatment of the COMTRADE format, please refer to the respective literature.
The les can be analysed with the Thyvisor software or with a standard compliant visualiser.
The number of recordings that can be saved is variable, depending on the user dened conguration
of the following parameters:
• Pre-trigger time and post-trigger time.
• Number of channels assigned to the measured values.
