Figure 10.80: Example of TESLA LITE Swing Record Choosing Watt, Var and Positive
Sequence Voltage Channels
Select an TESLA LITE swing record and expand the channels as shown. Click
the watt, var and positive sequence voltage; RecordGraph automatically eval-
uates and displays the positive sequence impedance.
Figure 10.81: Example of TESLA LITE Swing Record Choosing Impedance Channel
Select an TESLA LITE swing record and expand the channels as shown. Click
the impedance channel; RecordGraph automatically displays the positive se-
quence impedance trajectory.
As you select the desired channels, the impedance (R-X characteristics) are su-
perimposed on the existing relay characteristics. To select new set of voltage
and current channels use the
Delete trace(s) option from the right-click context
menu and select new channels. If desired, you can modify or re-apply the im-
pedance options.
