3.8.2.1 Impedance Relay Setting Screen
Figure 31 Impedance Relay Setting Screen
The relay setting screen sets the relay values to test the impedance or distance relay. The
settings determine if the relay passed or failed when the test completes.
•
The Reach setting value is in Ohms with a range of 0.000 to 99.99 ohms. The factory default
is 10 ohms.
•
There are two parts to defining the torque setting: lag or lead. A lagging torque uses a range
of 0-360
°
, and the lead/lag torque has a range of –180
°
to +180
°
. The torque angle value
has a range of 0.0 to 999.9. The default value will be set at 75
°
with current lagging voltage.
The user will only be able to enter a value of
±
180
°
if the
±
180
°
range is selected.
•
The Operating Time is the time in milliseconds with a range of 0 to 9999 milliseconds. The
factory default value is 100 milliseconds.
•
The Zone button is used to select the test label. The unit tests a single zone at one time and
has the information for that zone. The factory default is Zone 1 (Z1). The zone is used
during the save operation to separate test data for each zone to save data for all zones in a
single file. The Zones are Z1, Z2, Z3, Z4, Z5, Z2R, Z3R, Z4R, and Z5R.
•
The Target Tap has selectable values with a factory default of 0.2 DC amperes.
•
Select either Single-Phase, Three-Phase Y or Three Phase Open Delta modes with the
factory default set to Three-Phase Y. However, selecting the single-phase mode limits the
user to one V/I Generator.
The bottom of the screen has common buttons.
