6.5 RECORDS 6 ACTUAL VALUES
6
• Fault current and voltage in primary values
• Fault type
• Distance to the fault
The operation of this screen is similar to that of the previous oscillography screen, being in this case the number of fault
reports a fixed number (10), instead of variable and setting-selected like as in the previous case.
Once a fault report is selected, its heading description will be displayed, showing pre-fault information, fault information and
the distance to the fault. This file can be downloaded to the computer in a CSV format file.
Fault report file retrieval can be performed via serial or Ethernet communications. It must be taken into account that any
settings change in the fault report will produce the removal of all the information stored up to that moment.
6.5.4 DATA LOGGER
The access menu is
Actual > Records > Data Logger
. Once open, this menu will show a screen containing the
information monitored by the relay according to the settings adjusted at “
Setpoint > Product Setup > Data Logger
”, where
the user can select which analog channels will be recorded, as well as the sampling rate.
It must be taken into account that any settings change in the data logger will produce the removal of all the information
stored up to that moment.
The data logger screen diagram shows the time during which the displayed values have been obtained.
The upper part of the window shows the time when the oldest sample was taken, as well as the time when the most recent
value was taken.
Figure 6–11: DATA LOGGER
This screen offers the possibility of storing the data logger record obtained for a further analysis, in COMTRADE format.
Data Logger file retrieval can be performed only via Ethernet communications.
