Note
For double-ended fault locating, the devices at the ends must be configured with the
same data, i.e. if there is more than one line section, the values configured for device
B must mirror the data of device A. This means for two line types that line section 1
and 2 configured for device A must be line section 2 and 1 of device B.
If the devices are correctly configured, indication no. 1111 „FL active“ will be output
as ON.
If address 160 is set to 2 Sections or 3 Sections, the line impedance angle of
the first line section must be set at address 6001 S1: Line angle, the reactance
per unit length at address 6002 S1: x', and the capacitance per unit length at
address 6003 S1: c'. The line section length is entered at address 6004 S1: Line
length. All values refer to kilometer as distance measuring unit. If you want to use
miles as reference values, the addresses relevant for you are 6002, 6003 and 6004.
The central phase of your transmission tower layout is specified at address 6008 S1:
center ph.. Setting 6008 = unknown/sym. assumes a symmetrical layout.
Line sections 2 (A2) and 3 (A3) are configured in the same way as described above.
For setting values please refer to Table 2-15.
