6.5.2 WAVEFORM CAPTURE

The Actual > Records > Waveform Capture screen displays a list of all oscillography records available in the relay. The
G650 stores oscillography records from 1 to 999; this is the index of the obtained oscillography record. This screen allows
selecting the records to be saved among all records available. Download of these records will be done through the selected
connection in the "Communication > Computer" menu, either serial mode or Ethernet.

The screen will show all the available records in the Relay, and by clicking on each of them, the system will display the
heading information for that record, allowing downloading the information to a disk. Once the file to be downloaded has
been selected, the oscillography record can be opened using GE-OSC software.
GE-OSC is GE proprietary software that is not distributed together with EnerVista 650 Setup. This program is A
COMTRADE viewer and analysis software for oscillography files.
If the user does not have the GE-OSC tool, the oscillography record can be stored and viewed using any other analysis tool
capable of reproducing COMTRADE.1999 files.
When using GE-OSC software, this program requires the use of a template for each relay. If there is a stored template for
G650 relays (as in the figure), the user must simply select it and click the Open Selected Template key. The program will
then be prepared to view oscillography and digital records using the options in available menus (Waveforms and Digital
Flags). Otherwise, it will be required to select the Create New Template option, where the program will help create a new
template. Nevertheless, there is a specific instruction manual for GE-OSC software use.
