4.4.8 WAVEFORM CAPTURE (TRACE MEMORY)

The 750/760 PC Program can be used to view Waveform Capture or Trace Memory data stored by the relay.

Data is captured for analog current and voltage inputs (

Isg

) as well as digital data

for the output relays and the contact inputs states.

To use the Waveform Capture function, run the 750/760 PC Program and establish communications with a

connected 750/760 relay.

Select

Actual > Waveform Capture

from the main window to open the Waveform Capture window. The win-

dow shown below will appear, showing the Phase A current of the last captured waveform. The red vertical line

shows the trigger point of the waveform.

The cursors (shown by a solid and dotted green line) can be moved to different points on the waveform to see

magnitude and delta time information. Waveform data can be saved to a CSV (Comma delimited) file by press-

ing the

Save

button. The

Open

button can open waveform data that has been stored to a CSV file.
