5.2.4.4 OSCILLOGRAPHY FILES 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). 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 three files (*.DAT, *.HDR, *.CFG) that form the oscillography record in the
COMTRADE standard will be retrieved, and they will be viewed automatically if the GE-OSC software is installed in the
computer. Retrieved oscillographies can be viewed using any Comtrade viewer. The EnerVista 650 Setup software stores
by default oscillography records in the folder “.\EnerVista 650 Setup\files\osc”, 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 retrieval can be done using serial communication (ModBus RTU) or Ethernet (tftp).
5.2.5 DATA LOGGER
The G650 data logger can store information of up to 16 analog channels, among all channels available in the relay, with a
sampling rate selectable by setting. The memory of the data logger is fixed, 64 Kilobytes. Two bytes are needed per
channel. The selected channels will take all the available memory space. Therefore, the storage days will depend on the
selected number of channels and sampling rate.
