Plot Power Circle Diagram of Transmission System.

This class is designed to plot the power circle diagram of a transmission system both sending and receiving ends.

Examples

>>> import math, cmath
>>> from electricpy import visu
>>> visu.PowerCircle(
...     power_circle_type="receiving",
...     A=cmath.rect(0.895, math.radians(1.4)),
...     B=cmath.rect(182.5, math.radians(78.6)),
...     Vr=cmath.rect(215, 0),
...     Pr=50,
...     power_factor=-0.9
... )
