5.2.3.3 FAULT REPORT STATES
States associated to the fault report (“
Actual >Status>Records Status > Fault Reports
”), are shown on Table 5–10:
Table 5–10: FAULT REPORT STATES
FAULT REPORT TRIGG:
The activation of this state initiates the calculation of the fault location and the generation of
the corresponding report.
CLEAR FAULT REPORTS:
The activation of this state produces the removal of all faults stored in the relay. Additionally,
all active faults on the HMI display will be acknowledged. This signal is programmed at
“
Setpoint>Relay Configuration>Protection Elements
”.
FAULT DATE:
Date and time of the last fault.
FAULT TYPE:
Type of the last fault produced (3PHASE, AG, BG, CG, AB, ABG, BC, BCG, CA, CAG, NAF).
NAF indicates that the type of fault has not been calculated.
FAULT LOCATION:
Calculated distance to the last fault (the metering element will be the same used for setting
the line length).
FAULT REPORT NUMBER:
Number of the fault report file saved in the relay’s non-volatile memory, associated to the
last fault produced.
5.2.3.4 FAULT REPORT RETRIEVAL
Fault report files can be retrieved using the EnerVista 650 Setup software, or the web server at “http:\\relay IP address”.
For obtaining fault reports using the EnerVista 650 Setup software, the user must access “
Actual>Records>Fault report
”.
The top of the window shows the number of the last fault report stored by the device (Fault Record Number). Clicking on
the “View header” button, the system will show the header of the record selected at “Select Record”.
Clicking on the “Download” button, the file is retrieved, and saved in a folder selected by the user. The file name is
“FLTxxx.DAT”, where xxx is the corresponding record number. The fault report retrieval can be done using serial
communication (ModBus RTU) or Ethernet (tftp).
Fault reports are stored in the relay’s non-volatile memory, so they are accessible from the EnerVista 650 Setup software or
the relay’s web server. The fault report is a text file named FLTxxx.txt where xxx is the record number, with a range of 001
to 999. Only files from the 10 last faults will be stored. If there are already ten files stored and a new fault occurs, the new
fault will overwrite the oldest one. Enabling Show Fault on HMI option, this information will also be sent to HMI.
When a fault is produced and a warning message is displayed on the HMI, fault information alternates between two
separate screens: one with general information, and a second one with the fault metering values. This screen needs to be
acknowledged by the user by pressing the INTRO button to exit the fault report screen. If several consecutive faults are
produced, the HMI will always display the most recent one. Each stored fault will need to be acknowledged up to a
maximum of 10 faults. The HMI menu offers an option to view the last 10 faults produced, that menu displays both the
general information screen and the metering screen for each fault.
