electricpy.short_circuit_current(V, Z, t=None, f=None, mxcurrent=True, alpha=None)[source]

Short-Circuit-Current (ISC) Calculator.

The Isc-RL function (Short Circuit Current for RL Circuit) is designed to calculate the short-circuit current for an RL circuit.

Note

Also available as iscrl.

Parameters:

  • V (float) – The absolute magnitude of the voltage.

  • Z (float) – The complex value of the impedance. (R + jX)

  • t (float, optional) – The time at which the value should be calculated, should be specified in seconds, default=None

  • f (float, optional) – The system frequency, specified in Hz, default=None

  • mxcurrent (bool, optional) – Control variable to enable calculating the value at maximum current, default=True

  • alpha (float, optional) – Angle specification, default=None

Returns:

  • Opt 1 - (Irms, IAC, K) (The RMS current with maximum DC) – offset, the AC current magnitude, and the asymmetry factor.

  • Opt 2 - (i, iAC, iDC, T) (The Instantaneous current with) – maximum DC offset, the instantaneous AC current, the instantaneous DC current, and the time-constant T.

  • Opt 3 - (Iac) (The RMS current without DC offset.)
