electricpy.fault.indmachphs3sc(t, Is0, Lr, Ls, Lm, Rr, Rs, wrf=
0, freq=60, real=True)[source]¶ Induction Machine 3-Phase SC Calculator.
Determines the short-circuit current at a specified time for a three-phase fault on an unloaded induction machine.
- Parameters:¶
- t : array_like¶
The time at which to find the current, may be int, float, or numpy array.
- Is0 : complex¶
The initial (t=0) current on the stator.
- Lr : float¶
Inductance of the Rotor (in Henrys).
- Ls : float¶
Inductance of the Stator (in Henrys).
- Lm : float¶
Inductance of the Magnetizing branch (in Henrys).
- Rr : float¶
Resistance of the Rotor (in Ohms).
- Rs : float¶
Resistance of the Stator (in Ohms).
- wrf : float, optional¶
Frequency (in radians/sec) of the rotor slip. default=0
- freq : float, optional¶
Base frequency of the system (in Hertz). default=60
- real : bool, optional¶
Control argument to force returned value to be real part only. default=True
- Returns:¶
ias – Fault Current
- Return type:¶
array_like
