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.

\[Z_{sum} = Z_{1/2} + Z_{2/3} + Z_{3/1}// Z_1 = \frac{Z_{1/2}*Z_{3/1}}{Z_{sum}}// Z_2 = \frac{Z_{1/2}*Z_{2/3}}{Z_{sum}}// Z_3 = \frac{Z_{2/3}*Z_{3/1}}{Z_{sum}}\]

\[Z_{ms} = Z_1*Z_2 + Z_2*Z_3 + Z_3*Z_1// Z_{2/3} = \frac{Z_{ms}}{Z_1}// Z_{3/1} = \frac{Z_{ms}}{Z_2}// Z_{1/2} = \frac{Z_{ms}}{Z_3}\]

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 }
