emf.base._BasePhase¶

class emf.base._BasePhase(name, diameter, voltage, current, phase_angle, num_wires, spacing, ph_type, in_deg)[source]¶

A base class for creating a transmission line phase.

Parameters:

Parameters:	name : str The name of the phase. diameter : float The diameter of the wire. voltage : float The phase voltage. current : float The current in the phase. phase_angle : float The phase angle. num_wires : int The number of wires in the bundle. spacing : float The bundle spacing. ph_type : {‘ac3’, ‘dc’} The phase type. Use ‘ac3’ for 3-phase alternating current and ‘dc’ for direct current. in_deg : bool Specify True if input phase angle is in degrees; False if angle is in radians.

name : str: The name of the phase.
diameter : float: The diameter of the wire.
voltage : float: The phase voltage.
current : float: The current in the phase.
phase_angle : float: The phase angle.
num_wires : int: The number of wires in the bundle.
spacing : float: The bundle spacing.
ph_type : {‘ac3’, ‘dc’}: The phase type. Use ‘ac3’ for 3-phase alternating current and ‘dc’ for direct current.
in_deg : bool: Specify True if input phase angle is in degrees; False if angle is in radians.
