electricpy.dynetz(delta=None, wye=None, round=None)[source]¶

Delta-Wye Impedance Converter.

This function is designed to act as the conversion utility to transform delta-connected impedance values to wye- connected and vice-versa.

$$Z_{sum}=Z_{1/2}+Z_{2/3}+Z_{3/1}//Z_1=\frac{Z_{1/2}\ast Z_{3/1}}{Z_{sum}}//Z_2=\frac{Z_{1/2}\ast Z_{2/3}}{Z_{sum}}//Z_3=\frac{Z_{2/3}\ast Z_{3/1}}{Z_{sum}}$$

$$Z_{ms}=Z_1\ast Z_2+Z_2\ast Z_3+Z_3\ast Z_1//Z_{2/3}=\frac{Z_{ms}}{Z_1}//Z_{3/1}=\frac{Z_{ms}}{Z_2}//Z_{1/2}=\frac{Z_{ms}}{Z_3}$$

Parameters:¶

delta : tuple of float, exclusive¶

Tuple of the delta-connected impedance values as: { Z12, Z23, Z31 }, default=None

wye : tuple of float, exclusive¶

Tuple of the wye-connected impedance valuse as: { Z1, Z2, Z3 }, default=None

Returns:¶

• delta-set (tuple of float) – Delta-Connected impedance values { Z12, Z23, Z31 }

• wye-set (tuple of float) – Wye-Connected impedance values { Z1, Z2, Z3 }
