This information is part of the Modelica Standard Library maintained by the Modelica Association.

The quasi-static flux tubes library is based on the transient library Magnetic.FluxTubes. The main principles of confined flux and flux tubes apply, too. The quasi-static flux tubes library contains components for modelling of electromagnetic devices with lumped magnetic networks based on quasi-static theory. Models based on this library are suited for quasi-static simulation of transformers at component and system level.

The quasi-static components of this library do not consider saturation since linearity is strictly assumed. In case that the permeability of a saturated circuit needs to be considered, a transient permeability estimation sensor is provided do determine the effective permeability from a transient simulation.

A general introduction into quasi-static (quasi-static) phasor can be found in Modelica.Electrical.QuasiStatic.

This user's guide gives a short introduction to the underlying concept of quasi-static magnetic flux tubes, summarizes basic relationships and equations.
