LCC Ripper 🔪

A simple tool to slice ATPDraw LCC objects into several sections.

LCC Ripper 🔪

As Jack would say: let's go by parts.

LCC Ripper is intended to slice a transmission line model built in ATPDraw into several sections of arbitrary length. This tool makes a fine addition to ATP-Batlab when carrying out parametric studies in which the user is interested in varying the position where a disturbance occurs along a transmission line.

Instructions are pretty straightforward: open ATPDraw and build your LCC object from scratch. Save your model as an XML file. Launch the file lccripper.mlapp from MATLAB IDE, specify the source file, the total line length and the number of sections desired. Hit the button and that's it. Simple, efficient, brutal, just like Jack.

FAQ

• I loaded my file and it does not work!

  It does. Make sure your are using a XML export and not the standard binary ACP file of ATPDraw.

• Why should I use this instead of a $PARAMETER to set a variable for the faulted section length?

  You should not. It's up to you, but have in mind that JMarti models "hard-code" the line length into the poles and residues of the propagation function that are written into the PCH file. Good luck in meddling with that for adjusting line lengths.

• Why should I split my line model into hundreds or thousands of subdivisions?

  This is not about "we should". It's about "we can".
