5 SETPOINTS
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 "setpoints>Relay
Configuration>Protection Elements".
FAULT DATE: Date and time of the last fault produced.
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 unit will be the same used for setpoint the line
length).
FAULT REPORT NUMBER: Number of the fault report file saved in the relay non-volatile memory, associated to the last
fault produced.
5.2.3.4 FAULT REPORT RETRIEVAL
Fault report files can be retrieved using EnerVista 650 Setup software, or the web server at "http:\\relay IP address".
For obtaining fault reports using 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 folder "..\EnerVista 650 Setup\files\osc", using
"FLTxxx.DAT", where xxx is the corresponding record number. The fault report retrieval can be done using serial
communication (ModBus RTU) or Ethernet (ftp, tftp).
Fault reports are stored in the relay non-volatile memory, so that they are accessible from the EnerVista 650 Setup software
or the relay 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, this most
recent file will overwrite the oldest file. Afterwards, the fault information is sent to the HMI shared memory, to enable the
corresponding indicators to display the fault on the HMI display (if this option has been enabled by setpoint).
When a fault is produced and a warning message is displayed on the HMI, fault information alternates in 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, and each 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.
5.2.4.1 OVERVIEW
F650 units allocate 1-Mbyte of memory for storing oscillography records in RAM memory. These oscillography records are
restored in a non-volatile memory (relay Flash memory).
Oscillography records are stored in COMTRADE ASCII - IEEE C37.111-1999 standard format.
The oscillography module is in charge of storing instantaneous values of the 9 analog signals and the 16 digital signals
programmable at Setpoint > Relay Configuration > Oscillography in fault conditions (OSCILLO TRIGGER signal
activation).
All oscillography records store all analog signals (fixed) plus 16 digital signals (programmable). The order of storage in the
case of analog signals is as follows:
Analog 1IA channel.
