Distance Relay Settings
GARD 8000 Distance Relay RFL Electronics Inc.
Description Range Units Step Default
Local source zero sequence angle
Zero sequence impedance angle for the local source, in
degrees. Used for the fault locator. As the source impedance
value may differ depending on system configuration, use the
typical value.
5 - 90 deg 1 75
Remote source positive sequence magnitude
Positive sequence impedance magnitude for the remote source,
in secondary ohms. Used for the fault locator. As the source
impedance value may differ depending on system
configuration, use the typical value.
0.01 - 100 Ohm 0.01 1.25
Remote source positive sequence angle
Positive sequence impedance angle for the remote source, in
degrees. Used for the fault locator. As the source impedance
value may differ depending on system configuration, use the
typical value.
5 - 90 deg 1 75
Remote source zero sequence magnitude
Zero sequence impedance magnitude for the remote source, in
secondary ohms. Used for the fault locator. As the source
impedance value may differ depending on system
configuration, use the typical value.
0.01 - 100 Ohm 0.01 1.25
Remote source zero sequence angle
Zero sequence impedance angle for the remote source, in
degrees. Used for the fault locator. As the source impedance
value may differ depending on system configuration, use the
typical value.
