4.2.5.3 Line parameter for Fault location (LD

FLrate)
Enter the line parameter of the selected logical device within the range of 0.001 to 30.000.
LD

FLrate is a line parameter, which depends on the fault location result expressed as an
impedance (

) or a distance (km). (Note:

means Logical device number.)
(1) In case of the fault distance in km FltDiskm:
If the fault location result is reported as a distance (km) from IEC60870-5-103,
Fault location value (FltDiskm.mag,f) = [Fault location value in km (IEC103)]
/
[LD

FLrate]
Set the [LD

FLrate] = 1.000 (Note: Default setting value is 1.000)
If the fault location result is reported as an impedance (

) from IEC60870-5-103,
Fault location value (FltDiskm.mag,f) = [Measurement value in

(IEC103)] / [LD

FLrate]
Set the [LD

FLrate] = 1
/
[Line impedance per km]
(2) In case of the fault impedance FltZ:
If the fault location result is reported as a distance (km) from IEC60870-5-103,
Fault location value (FltZ.cVal.mag,f) = [Measurement value in km (IEC103)]
