GEK-106310-AF F650 DIGITAL BAY CONTROLLER 5-21
OSC DIGITAL CHANNEL XX: These states are configured at “ Setpoint>Relay configuration>Oscillography ”. Each
of these states can be associated with a protection state or to a virtual output. Each
oscillography record reflects the changes experienced by this state during the record.
OSCILLO TRIGGER: The activation of this state produces the oscillography record capture. Each record
uses a percentage of its capacity to store prefault information. This percentage is
selected in the Trigger Position setting, and the rest of the record’s capacity stores
post-fault information.
NUMBER OF TRIGGERS: This is the number of the most recent oscillography record stored in the relay. The
record is stored in COMTRADE format. The range is 0 to 999.
CYCLES PER RECORD: This state displays the number of cycles that are stored in each oscillography record.
Although the number of cycles can be a decimal number, the record represents only
the integer part.
AVAILABLE RECORDS: This shows the number of records stored in the relay, which can be retrieved by serial
communication (ModBus RTU) or Ethernet (ftp, tftp). The range is 0 to 20.
5.2.4.3 Oscillography file retrieval
Oscillography files can be retrieved using the EnerVista 650 Setup software, or the web server at “http:\\relay IP address”.
To obtain the oscillography records using the EnerVista 650 Setup software, go to “
Actual>Records>Waveform capture ”.
The top of the window shows the number of the last oscillography record stored by the device (Newest Record Number),
followed by the maximum number of oscillos available (Available Records in Device). Click
View header to show the header
of the record selected at Select Record .
Click Download and the three files (*.DAT, *.HDR, *.CFG) that form the oscillography record in the COMTRADE standard are
retrieved and viewed automatically if the GE-OSC software is installed in the computer. Retrieved oscillography records
can be viewed using any Comtrade viewer. The EnerVista 650 Setup software stores oscillography records in the folder
“.\EnerVista 650 Setup\files\osc” by default, in the same directory where the program is installed. The file names are
“OSCxxx.DAT”, “OSCxxx.CFG”, “OSCxxx.HDR”, where xxx is the corresponding record number. The oscillography record
retrieval uses serial communication (ModBus RTU) or Ethernet (ftp, tftp).
5.2.5 Data logger settings
The F650 data logger can store information from up to 16 analog channels, among all channels available in the relay, with
a selectable sampling rate. The memory of the data logger is fixed at 64 Kilobytes with two bytes needed per channel. The
selected channels take all available memory space, therefore, the number of days of storage depends on the selected
number of channels and sampling rate.
