electricpy.phs3valpha(VA, VB=0, VC=0)[source]¶

Three-Phase V-Alpha Calculator.

Accepts the three-phase voltages for which the accumulated Alpha voltage should be calculated.

\[V_{\alpha}=V_A-\frac{V_B}{2}-\frac{V_C}{2}\]

Parameters:

VA ([float, complex]) – A-phase voltage, (or tuple/list of voltages), unitless.
VB ([float, complex], optional) – B-phase voltage, unitless.
VC ([float, complex], optional) – C-phase voltage, unitless.

Returns:

Valpha – Alpha-voltage as calculated from input three-phase voltages. Matches type of inputs.

Return type:

[float, complex]
