Information

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

Calculates rotor lagging angle by measuring the stator phase voltages, transforming them to the corresponding space phasor in stator-fixed coordinate system,
rotating the space phasor to the rotor-fixed coordinate system and calculating the angle of this space phasor.

The sensor's housing can be implicitly fixed (useSupport=false).
If the machine's stator also implicitly fixed (useSupport=false), the angle at the flange is equal to the angle of the machine's rotor against the stator.
Otherwise, the sensor's support has to be connected to the machine's support.
