Transformer Pi-model impedance that accurately reflects impedance for transformers with 2 or 3 windings. For transformers with 4 or more windings, you must use TransformerInfo.

Method Details

[hide private]

init(self, x=0.0, g=0.0, r0=0.0, r=0.0, b=0.0, g0=0.0, x0=0.0, b0=0.0, Windings=None, *args, **kw_args)
(Constructor)

Initialises a new 'WindingPiImpedance' instance.

Parameters:

x - Positive sequence series reactance of the winding. For a two winding transformer, the full reactance of the transformer should be entered on the primary (high voltage) winding.
g - Magnetizing branch conductance (G mag).
r0 - Zero sequence series resistance of the winding.
r - DC resistance of the winding.
b - Magnetizing branch susceptance (B mag). The value can be positive or negative.
g0 - Zero sequence magnetizing branch conductance.
x0 - Zero sequence series reactance of the winding.
b0 - Zero sequence magnetizing branch susceptance.
Windings - All windings having this Pi impedance.
