Linemod can be saved on your remote terminal by simply clicking the
on the above link. The file is a .tar file and has
been compressed. To retrieve the file type "tar xvf temp.tar" This
will expand the file and place it in a directory named "line". Please make
sure that a directory with this name does not already exist.
In the "line" directory will be two subdirectories: "cfiles" and "docs". The
"docs" subdiretory will contain a "README" file which will explain how the
program works. The "cfiles" subdirectory contains all the relevant
programs to run linemod.
Linemod determines the input/output voltage relationship between two ends
of a transmission line. It allows several components to be added between the
ends of the transmission lines including series and shunt resistances,
capacitances, and inductances, as well as bridge taps (what can also have
these elements). Furthermore, it allows several different types of
wires. Other elements can be added easily by examining the source
code. For example, series_r.c contains the ABCD parameters for a shunt
resistance. This could be modified to support other components. More
wires can also be added via the primary function in line.c.
An important note is that if a file describing the line characteristics
has been changed, then the previously created output files must be
deleted. Otherwise, the program may not overwrite the old files.
The above tar file has been updated with new line characteristics:
These lines use characterstics from T1E1/98-117R13 instead of
T1E1/95-117R4.
