<CblName>, <CblPermittivity>,
<CblAtt1>, <CblFreq1>{, <CblAtt2>, <CblFreq2>}...
Defines a new user-defined cable type for Distance to Fault (DtF) measurements.
The cable's frequency-dependent attenuation is defined via attenuation/frequency pairs
<CblAtt1>, <CblFreq1>, <CblAtt2>, <CblFreq2>, ...
. At least one pair
has to be specified.
Suffix:
<Chn>
.
Channel number
This suffix is ignored: cable types are defined for all channels.
Setting parameters:
<CblName>
Name of the cable type.
Must be unique among all DtF cable types, with case insensitive
match.
<CblPermittivity>
Relative permittivity ε
r
of the cable type.
<CblAtt[i]>
Attenuation value
i
in the frequency-dependent attenuation table
of the cable type.
Default unit: dB/m
<CblFreq[i]>
Frequency
i
in the frequency-dependent attenuation table of the
cable type.
Default unit: Hz
Example:
CALCulate:TRANsform:DTFault:DEFine 'My cable
type', 1.1, 0.01, 1GHz, 0.015, 2GHz, 0.012,
3GHz
Defines a new cable type "My cable type" with relative permittiv-
ity ε
r
=1.1 and the frequency-dependent attenuation given in the
table below.
