How to handle branches with RATEA=0

Hello everyone!

I would like to know what is the best practice when encountering branches with RATEA=0. In the PSSE -pandapower parser they basically ignore the RATEA and set a very large value the maximum current in the line. (Considering a RATEA= 0 leads to a max current =0).

Any suggestions?

RATEA=0 means that no current limit is defined for rate A. It is equivalent to infinite current capacity and the rate will be ignored in all overload reports.

The approach in Pandapower seems correct.

Thank you very much for the quick answer! I find as well RATEA=1 from time to time. Does this have another meaning? In general, is this convention explained somewhere in the PSSE manual? Thanks!

That means that the rate is 1 MVA.
