Fault Module¶

Fault calculation module exposes classes capable of running ERACS Fault studies.

class TEracsFault¶

Low-level implementation of the Fault interface. All methods in this class provide low-level functionality involving direct interactions with the DLL. Contains minimal logic and safety checks.

Inherits: Calculations.TEracsModuleLoadflowDependent.

property VersionNumber¶

Version number of the calculation module.

Type: str.
Writable: False.

property ProgramNumber¶

Program number of the calculation.

Type: int.
Writable: False.
Example: 1 = Loadflow

ChangeImpedance(ASeqNum, AStatorR, AReactance)¶

Change the impedance for a given synchronous machine.

Parameters

ASeqNum (int) – Sequence number of machine to change impedance of.
AStatorR (float) – The stator resistance of the machine.
AReactance (float) – The transient reactance of the machine.

Raises

TEracsArgumentError – If the arguments are of the incorrect type.
