QB64PE at work

[bobalooie]

I'm an electrical power engineer by profession. Frequently I need to calculate the available short circuit current in a circuit (electrical code requirement). I have very fancy analysis programs to calculate fault currents in a large system (say an entire building), but occasionally I need to quickly calculate a short circuit current for a single circuit or a very small network.

There is a well-documented method to calculate a short circuit current from point A to point B. Doing the calculation by hand is a PITA. So I put together a utility to do the calculation with a form-style data entry to avoid having to refer to all those tables.

The method's conductor constants as published only work on 60 Hz power systems. The conductor constants are invalid on 50 Hz power systems because the overall impedances are different. I haven't located an equivalent set of tables for 50 Hz systems, but I would be surprised to find they don't exist somewhere.

I plan to extend this to allow me to retrieve results from other studies and create a network in one overall project.

Real life QB64PE paying me back for all that money I spent on it.
