Short-Circuit Calculation acc. IEC 60909 (VDE 0102)

ATPDesigner also supports the most important features of the short-circuit calculation acc. the standard IEC 60909-0:2001, July 2002 (VDE 0102). This feature can be also used for educational purposes.

Please note, that it is recommended to study the standard IEC 60909 before using this feature of ATPDesigner.
