modelConductor
Single-phase linear conductor
Extends from Interfaces.OnePort (Two pins, current through), Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
Information
The linear conductor connects the voltage v with the
current i by i = v*G.
The conductance G is allowed to be positive, zero, or negative.
The conductor model also has an optional conditional heat port. A linear temperature dependency of the conductance is also taken into account.
