This information is part of the Modelica Standard Library maintained by the Modelica Association.
This package contains basic space phasor models.
Real and imaginary part of voltage space phasor are the potentials v_ of the space phasor connector; (implicit grounded).
Real and imaginary part of current space phasor are the currents i_ at the space phasor connector;
a ground has to be used where necessary for currents flowing back.
