82 Practical examples
Note:
Some generator manufacturers give equivalent circuit data for delta connection. In
that case the given reactance values must be divided by three.
Transformation ratio between the
stator and the rotor. Defined when
rotor shaft is mechanically locked
and nominal stator voltage is fed to
the stator windings.
