Demo Version of ARCO is ready to try

Please note: that this is not the final version. The demo version of the final ARCO is not offered via the internet.

Some Comments:

1. ARCO coordinates all Overcurrent and Earth Fault relays in a high voltage substation.

2. Documentation:  ARCO offers detailed step by step calculations as well as an abstract result.

3. ARCO is not a short circuit calculator. You need another typical short circuit program together with ARCO

4. ARCO is not a Grid Modelling Software. It is a Substation’s protective model maker.
