.. py:function:: delta_to_star(impedance_a: complex, impedance_b: complex, impedance_c: complex) -> list[complex]

   Convert's delta impedance arrangement to star

   Examples:
   1.) Impedance with resistances and zero reactance
   >>> delta_to_star(complex(3,0),complex(5,0),complex(7,0))
   [(2.3333333333333335+0j), (1.4+0j), (1+0j)]

   2.) Impedance with resistance and reactance
   >>> delta_to_star(complex(1,3),complex(2,0),complex(0,-3))
   [-2j, (3-1j), (0.6666666666666666+2j)]

   3.) Zero impedance
   >>> delta_to_star(complex(0,0),complex(1,2),complex(1,6))
   Traceback (most recent call last):
     ...
   ValueError: entered impedance value is zero

   4.) Negative resistance
   >>> delta_to_star(complex(12,0),complex(-1,2),complex(1,6))
   Traceback (most recent call last):
     ...
   ValueError: entered resistance value is negative
