The results are aggregated by object and presented in detail in tabular form via the "Details" button in the detail results form of nodes and cables/lines.
The results can also be exported to Excel.
The calculation reports on seven problems:
•Not switched off
•Margin too small
•Not selective
•Causes overloading
•Not disconnected, on refusing
•Not selective, on refusing
•Causes overload, on refusing
Details of all short circuits are reported on:
•Fault distance: simulated fault distance (%) in the fault object (if cable or line)
•Fault type: simulated short circuit
•Fault resistance: fault resistance (Ohm) of the simulated short circuit
•Refusing: any refusing circuit breaker
•Not disconnected: whether the short circuit is not completely disconnected
•Margin too small: whether the current through any tripping protection is only barely (less than 20%) greater than the minimum set current
•Not selective: whether the short circuit is not selectively tripped
•Causes overload: whether any branch is thermally overloaded or current overloaded during or after the short circuit, respectively
Color indication
Nodes, cables and lines are displayed with the color Too High if there is a problem.
The colors can be defined in the Options, under Calculation | General.
