electricpy.fault.short_circuit_mva¶
- electricpy.fault.short_circuit_mva(Zth=None, Isc=None, Vth=1)[source]¶
Short-Circuit MVA Calculator.
Function defines a method of interpretively calculating the short-circuit MVA value given two of the three arguments. The formulas are all based around the following:
\[MVA_{sc} = V_{th}*I_{sc}\]\[V_{th} = I_{sc}*Z_{th}\]- Parameters:
Zth (float) – The Thevenin-Equivalent-Impedance
Isc (float, optional) – Short-Circuit-Current, if left as None, will force function to use default setting for Vth. default=None
Vth (float, optional) – The Thevenin-Equivalent-Voltage, defaults to a 1-per-unit value. default=1
- Returns:
MVA – Short-Circuit MVA, not described as three-phase or otherwise, such determination is dependent upon inputs.
- Return type:
float
