If multiple line sections (address
160
=
2 Sections
or
3 Sections
) are set, you must set the following pa-
rameters.
For line section 1 set the addresses:
•
6009
S1: XE/XL
,
•
6010
S1: RE/RL
or
•
6011
S1: K0
,
•
6012
S1: angle K0
.
For line section 2 set the addresses:
•
6029
S2: XE/XL
,
•
6030
S2: RE/RL
or
•
6031
S2: K0
,
•
6032
S2: angle K0
.
For line section 3 set the addresses:
•
6049
S3: XE/XL
,
•
6050
S3: RE/RL
or
•
6051
S3: K0
,
•
6052
S3: angle K0
.
Note
Double-ended fault location requires that the devices are configured with the same data at both ends, 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
= 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 2-16.
